Question

Y-4/x = a solve for y

Answer 1

y = a + 4/x

Explanation:

-add 4/x to both sides: y - 4/x + 4/x = a + 4/x

- simplify: y = a + 4/x

Answer 2

see below

Explanation:

solve for y

y-4/x = a

Add 4x to each side

y-4/x+4/x = a+4x

y = a+4x

If the equation is

(y-4)/x = a

Multiply each side by x

(y-4)/x *x = a*x

y-4 = ax

Add 4 to each side

y = ax+4
