Solve Multi-Step Equations with Integers

Finding the values of a variable that make an equation true

• Means

• Expand

• Solve

• Simplify

An equation that requires more than one step to solve.

• One Step Equation

• Linear Equation

• Literal Equation

• Multi-Step Equation

Second step in solving equations is:

• Get the variables on one side of the equation and combine like terms

• Multiply or divide both sides to solve.

• Remove symbols of grouping (Parenthesis)

• Get the numbers on the other side, away from the variables

the process of finding all values of the variable that make the equation a true statement 

• formula

• solve an equation

• unit rate

• identity

20  + a  =  -50

• a = -950

• a =  -70

• a = -31

• a = -50

4x + 10 = -26

• 4

• -4

• -9

• 9

12x - 15 = 3(2x+3)

• x = 4

• x = -4

• x = 2

• x = -2

Solve:
5y + 34 = -2(-7y+1)

• y = -4

• y = 9

• y = 4

• y = 36/19

10x + 9 = 4x - 9

• 0

• 3

• -3

• -18

The goal of solving a one, two, or multi-step equations is to:

• Find the constant

• Find the coefficient

• Find the value of the variable
