Question

a) 3(x+1)+2(2x-3) = 5(x-1) +8
n) 2(x-1) + 3 (x + 1) = 4(x + 2)
c) 3X+5+2X+6=X+2²
d) 3 ( x + 1) + 2(2x-3) = 5(x-1) + 8

Answer 1

Resposta:

Explicação passo a passo:

A)3(x+1)+2(2x-3)=5(x-1)+83

3x+3+4x-6=5x-5+8

3x-4x-5x=3-6-5-8

-4x=-6(-1)

x=4/6

B)2(x-1)+3(x+1)=4(x+2)

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

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

-3x=-7(-1)

x=7/3

c)3x+5+2x+7=x+2²

3x-2x-x=5-6-2²

1x=-3

x=1/-3

d)3(x+1)+2(2x-3)=5(x-1)

3x-3+4x-6=5x-5+8

3x-4x-5x=3-6-5-8

-4x=-6(-1)

x=4/6
