## Algebra 1 Tutorial

#### Intro

The following is an example of an equation that requires multiplication, addition and subtraction knowledge with variables. This equation is solving for X. The final result should include variable X on one side of the equal sign with an number on the other.

4(x+6)= -20

-11

-12

-5

5

2

#### Solution

1. The number outside the parentheses must be multiplied by the variable and and digit inside while keeping the same format: 4 x n= 4n 4 x 6=20

2. This creates a new equation:
4x+24= -20

3. The goal is to get x by itself. The first logical step is to have the 24 equal to 0 on the side with the variable. To obtain this 24 must be subtracted from both sides.
4x + 24 (-24) = -20 – 24
since 24 – 24 =0 this leaves and -20 – 24= -44
4x = -44

4. X is still not alone. The final step is to divide 4 by both sides.

4X = -44 4X/4= 1X or X and -44/4= -11
— —
4 4

5. Final result x=-11
