Solve the following equation
|-4y|=-8
Solve for y
|-4y| = -8
Absolute Value Equations
Since this is an absolute value equation
Setup two equations
- -4y = -8
- -4y = 8
Solve Equation 1 → -4y = -8
Divide each side of absolute value equation 1 by -4
Keep our =
| -4y | |
| -4 |
| = |
| -8 |
| -4 |
Solution to absolute value equation 1 is
y = 2
Solve Equation 2 → -4y = 8
Divide each side of absolute value equation 2 by -4
Keep our =
| -4y | |
| -4 |
| = |
| 8 |
| -4 |
Solution to absolute value equation 2 is
y = -2
