Question

Resolva essa Equação:

5(x-1)-2(3x+1)=4(5-x)

Answer 1

$\mathsf{5(x-1)-2(3x+1)=4(5-x) }$

$\mathsf{ 5x-5-6x-2=20-4x}$

$\mathsf{ -x-7=20-4x}$

$\mathsf{ -x+4x=20+7}$

$\mathsf{ 3x=27}$

$\boxed{\boxed{\mathsf{ x=9}}}$

Answer 2

Resposta:

9

Explicação passo-a-passo:

$5.(x - 1) - 2.(3x + 1) = 4.(5 - x)$

$5x - 5 - 6x - 2 = 20 - 4x$

$5x - 6x + 4x = 20 + 2 + 5 \\ 3x = 27 \\ x = \frac{27}{3} = 9$
