Question

c)2(x-1)=3x+4
d)3(x-1)-7=15
e)7(x-4)=2x-3

Answer 1

c) 2x-2=3x+4
-1x=6
x=-6
D)3x-3-7=15
3x-10=15
3x=25
x=25/3
E)7x-28=2x-3
5x=25
x=5

Answer 2

c)2 (x - 1 ) = 3 x + 4
2 x - 2 = 3 x + 4
2 x - 3 x = 4 + 2
-1 x = 6
x = 6/-1
x = -6
d) 3( x - 1 ) - 7 = 15
3 x - 3 -  7 = 15
3 x - 10 = 15
3 x = 15 + 10
3 x = 25
x = 25/3
e) 7 (x - 4 ) = 2 x - 3 
7 x - 28  = 2 x - 3
7 x - 2 x = - 3  + 28
5 x  = + 25
x = 25/5
x = 5
