Absolute Value Equations
Since this is an absolute value equation
Setup two equations

• 2x+4 = 30
• 2x+4 = -30

Solve Equation 1 → 2x+4 = 30

Subtract - 4 from both sides of the equation

2x+4 - 4= 30 - 4
2x = 26

Divide each side of absolute value equation 1 by 2

Keep our =

2x
2

=

26

2

Solution to absolute value equation 1 is
x = 13

Solve Equation 2 → 2x+4 = -30

Subtract - 4 from both sides of the equation

2x+4 - 4= -30 - 4
2x = - 34

Divide each side of absolute value equation 2 by 2

Keep our =

2x
2

=

-34

2

Solution to absolute value equation 2 is
x = -17
