Question

A)5x=2x+3=
B)3(2-2X)=-7X=
C)4(2-2x)+7x=5(3+2x)=
D)6(x-3)=7(x+7)-16=

Answer 1

a) 5x = 2x + 3
5x - 2x = 3
3x = 3
x = 3/3
x = 1

b) 3(2 - 2x) =-7x
6 - 6x = -7x
-6x + 7x = -6
x = -6

c) 4(2 - 2x)+ 7x=5 (3+2x)
8 - 8x + 7x = 15 + 10x
-8x + 7x - 10x = 15 - 8
9x = 11
x = 11/9

d) 6 (x - 3)= 7 (x-7) - 16
6x - 18 = 7x - 49 - 16
-18 + 49 + 16 = 7x - 6x
x = 47
