(1/4)A - (1/4) = -2

A - 1 = -2*4 (multiply both sides of the equation by 4)

A = -8 +1 (perform the arithmetic, add 1 to both sides)

A = -7 (perform the arithmetic)

Check

(1/4)(-7) - (1/4) = -2

-7/4 - 1/4 = -2

-8/4 = -2 (yes)

A - 1 = -2*4 (multiply both sides of the equation by 4)

A = -8 +1 (perform the arithmetic, add 1 to both sides)

A = -7 (perform the arithmetic)

Check

(1/4)(-7) - (1/4) = -2

-7/4 - 1/4 = -2

-8/4 = -2 (yes)
