Answer
x = -12
Work Step by Step
$\frac{1}{5}$x - 1 = $-\frac{4}{5}$x - 13
Add $\frac{4}{5}$x to both sides:
$\frac{5}{5}$x - 1 = -13
x - 1 = -13
Add 1 to both sides:
x = -12
Check with substitution:
$\frac{1}{5}$(-12) - 1 = $-\frac{4}{5}$(-12) - 13
$\frac{-12}{5}$ - 1 = $\frac{48}{5}$ - 13
-1 = $\frac{60}{5}$ - 13
-1 = -1
