What is basic algebra?

Basic algebra is the language that the field of mathematics uses to talk about the abstract world of numbers. Arithmetic focuses on only real, defined numbers, but algebra focuses on how numbers work as a group and allows you to talk about unknown quantities.

How do you do algebra 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.

What is the first step in solving a system by substitution?

Here’s how it goes:

• Step 1: Solve one of the equations for one of the variables. Let’s solve the first equation for y:
• Step 2: Substitute that equation into the other equation, and solve for x.
• Step 3: Substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

How do you solve two equations with substitution?

To solve systems using substitution, follow this procedure:

1. Select one equation and solve it for one of its variables.
2. In the other equation, substitute for the variable just solved.
3. Solve the new equation.
4. Substitute the value found into any equation involving both variables and solve for the other variable.

What is substitution example?

In English grammar, substitution is the replacement of a word or phrase with a filler word such as “one”, “so”, or “do” in order to avoid repetition. Consider the following example from Gelett Burgess’ poem “The Purple Cow”. Notice how, in lines two and four, “one” is used in place of “The Purple Cow”.

How do you solve systems of equations by substitution?

Steps for Using the Substitution Method in order to Solve Systems of Equations

1. Solve 1 equation for 1 variable. ( Put in y = or x = form)
2. Substitute this expression into the other equation and solve for the missing variable.
3. Substitute your answer into the first equation and solve.
4. Check the solution.

How do you solve equations by elimination?

The Elimination Method

1. Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient.
2. Step 2: Subtract the second equation from the first.
3. Step 3: Solve this new equation for y.
4. Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.
