Question

a) 5(x - 2) = 3 (X+2).
b) 3(3x - 1) = - 2 (X+3)​

Answer 1

Resposta:

Explicação passo-a-passo:

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

5x-10=3x+6

5x-3x=6+10

2x=16

x=16/2

x=8

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

9x-3=-2x-6

9x+2x=-6+3

11x=3

x=3/11

Answer 2

Resposta:

A)

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

5x - 10 = 3x + 6

5x - 3x = 6 + 10

2x = 16

x = 16/2

x = 8

B)

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

9x - 3 = - 2x - 6

9x + 2x = - 6 + 3

11x = - 3

x = - 3/11

x = 0,27272...
