Question

Ayudenme paso a paso porfa...
a) 3x/2 - 1 = 5x +2

b) 3x/4 +6= 12

c) 3x/2 - 5 = x -4

Paso a paso please....

Answer 1

3x/2 -1= 5x + 2
3/2 x - 5x = 2 +1
(3x - 10 x)/ 2 = 3
-7/2 x= 3
x= 3÷( -7/2)
x = - 6/7
3/4x + 6 = 12
3/4 x = 12 -6
3/4x = 6
x= 6÷ (3/4)
x=8

3/2x -5= x-4
3/2x -x = -4 + 5
1/2 x= 1
x= 1÷ 1/2
x= 2
