Question

3(–3x + 5) + 3 – x = –4 – (2x – 2) + x – 8

Answer 1

Resposta:

$S=\{\frac{28}{9}\}$

Explicação passo-a-passo:

$3( - 3x + 5) + 3 - x = - 4 - (2x - 2) + x - 8 \\ - 9x + 15 + 3 - x = - 4 - 2x + 2 + x - 8 \\ - 9x - x + 2x - x = - 4 + 2 - 8 - 15 - 3 \\ - 9x = - 28 \\ 9x = 28 \\ \boxed{\boxed{x = \frac{28}{9}}}$

Answer 2

Explicação passo-a-passo:

3(–3x + 5) + 3 – x = –4 – (2x – 2) + x – 8

–9x + 15 + 3 – x = –4 + 2x + 2 + x – 8

–9x – x + 2× - x = –4 + 2 – 8 - 15 - 3

-11+2×= - 32

-9× = -32 (-1)

×= 28/9
