|-1|=4y
Variable y cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by y.
1=4y
The absolute value of a real number a is a when a\geq 0, or -a when a<0. The absolute value of -1 is 1.
4y=1
Swap sides so that all variable terms are on the left hand side.
y=\frac{1}{4}
Divide both sides by 4.
