What is an example of an equivalent expression?
Two expressions are said to be equivalent if they have the same value irrespective of the value of the variable(s) in them. Example 1: Are the two expressions 2y+5y−5+8 and 7y+3 equivalent? Explain your answer.
Which expression is equivalent to 2x 4y 3?
The answer is D. 2^3 is 8.
What is the slope of 2x 4y =- 3?
Rewrite in slope-intercept form. Using the slope-intercept form, the slope is 12 .
Which is the graph of 2x 4y 6?
The graph of 2x – 4y > 6 is in the far-right graphic image.
What is equivalent calculator?

BYJU’S online equivalent expression calculator tool makes the calculations and simplification faster and it displays the equivalent expression in a fraction of seconds.
What is the fraction equivalent of?
Fractions are equivalent if their simplest forms are the same. So, to make equivalent fractions, all you have to do is multiply the top number (the numerator) and the bottom number (the denominator) by the same number—and it can be any number, as long as you use the same one for both the top and bottom.
Are two equations equal?
Two systems of equations are equivalent if they have the same solution(s). Given a system of two equations, we can produce an equivalent system by replacing one equation by the sum of the two equations, or by replacing an equation by a multiple of itself.
What is the answer to 2 3x 10?
Divide both sides by 2, Thus, the solution of the given equation is 15.
How do you solve problems with two variables?
In a two-variable problem rewrite the equations so that when the equations are added, one of the variables is eliminated, and then solve for the remaining variable. Step 1: Multiply equation (1) by -5 and add it to equation (2) to form equation (3) with just one variable.
How do you solve for variables?
If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.
How do you solve equations algebraically?
Use elimination to solve for the common solution in the two equations: x + 3y = 4 and 2x + 5y = 5. x= –5, y= 3. Multiply each term in the first equation by –2 (you get –2x – 6y = –8) and then add the terms in the two equations together. Now solve –y = –3 for y, and you get y = 3.
How do we solve an equation for a particular variable?
To solve a formula for a specific variable means to get that variable by itself with a coefficient of 1 on one side of the equation and all the other variables and constants on the other side. We will call this solving an equation for a specific variable in general.
What is not a variable?
Consistent or having a fixed pattern; not liable to change. ‘a non-variable rate mortgage is the most stable option with little risk’ More example sentences.
