Question

a)3(×-2)=4(3-×)=
b)3(3×-1)=2(3×+2)=
me ajudem pff

Answer 1

a)3(x - 2) = 4(3 - x)
    3x - 6 = 12 - 4x
    3x + 4x = 12 + 6
            7x = 18
            x = 18 / 7



b)3(3x - 1) = 2(3x + 2)
         9x - 3 = 6x + 4
       9x - 6x = 4 + 3
               3x = 7
                 x = 7 / 3

Answer 2

a)
3(x - 2) = 4.(3 - x)
3x - 6 = 12 - 4x
3x + 4x = 12 + 6
7x = 18
x = 18/7

********************************
b)
3.(3x - 1) = 2.(3x + 2)
9x - 3 = 6x + 4
9x - 6x = 4 + 3
3x = 7
x = 7/3
