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

• 2x+6 = 47
• 2x+6 = -47

Solve Equation 1 → 2x+6 = 47

Subtract - 6 from both sides of the equation

2x+6 - 6= 47 - 6
2x = 41

Divide each side of absolute value equation 1 by 2

Keep our =

2x
2

=

41

2

Solution to absolute value equation 1 is
x = 20.5

Solve Equation 2 → 2x+6 = -47

Subtract - 6 from both sides of the equation

2x+6 - 6= -47 - 6
2x = - 53

Divide each side of absolute value equation 2 by 2

Keep our =

2x
2

=

-53

2

Solution to absolute value equation 2 is
x = -26.5
