The equivalent value of y from the expression if 4x - 5 = 7 + 4y is (x-3)/4

Given the expression

4x - 5 = 7 + 4y

We need to make y the subject of the formula:

Add 5 to both sides:

4x - 5 + 5= 7 + 4y + 5

4x = 12 + 4y

Subtract 12 from both sides

4x - 12 = 12 + 4y - 12

4x - 12 = 4y

y = (4x-12)/4

y = 4(x-3)/4

y = x-3/4

Hence the equivalent value of y is (x-3)/4
