Question

o) 4(2m-1) + 3m = 2(4m-1) - (2-m)
r) 3(x + 1) + 2 = 5 + 2(x - 1)
u) 2 (x-1) + 3(x + 1) = 4(x + 2)
x) 2(x – 3) + 8x +4 = 5 (x + 2)

Answer 1

Resposta:

O) 6m-4+3m=6m-2-2+m

6m+3m-6m-m=-4-2+4

2m=2

m=2÷2

R)3x+3+2=5+2x-2

3x-2x=5-2-3-2

x=-2

U) 2x-2+3x+3=4x+8

2x+3x-4x=8+2-3

x=7

X)2x-6+8x+4=5x+10

2x+8x-5x=10+6-4

5x=12

x=12÷5
