Question

a) 7(x - 5)-3(x + 1)=0
b) 3(x - 2) = 4(-x+3)
c) 2(x + 1) - (x - 1) = 0
d) 5(x + 1)-3(x+2) = 7
e) 4(x + 5) + 3(x + 5) = 21
f) 2(x + 5)-3(5 - x) = 10
g) 13 + 4(2x - 1) = 5(x + 2)
h) 8(x - 1) = 8 - 4(2x - 3)
i) -4(x - 2) – 2 = 2x

Answer 1

Resposta:

A)7x-35-3x+3=0

4x-32=0

4x=0+32

4x=32

X=32/4

X=8

Answer 2

A)7x-35-3x-3=0

7x-3x=35+3

4x=38
