Respuesta :
(3/4)*x-6 = 15 // - 15
(3/4)*x-15-6 = 0
3/4*x-21 = 0 // + 21
3/4*x = 21 // : 3/4
x = 21/3/4
x = 28
(3/4)*x-15-6 = 0
3/4*x-21 = 0 // + 21
3/4*x = 21 // : 3/4
x = 21/3/4
x = 28
subtract 6 from both sides you get 9
3/4x=9
multiply both sides by 4
3x=36
divide by 3 into both sides
x=12
3/4x=9
multiply both sides by 4
3x=36
divide by 3 into both sides
x=12
