Question

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

Answer 1

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

5 - 5x - 2x + 1= - 6 - 3x

- 5x - 2x + 3x= - 6 - 5 - 1

- 4x= - 12 >>.(-1)

4x= 12

x= 12/4

x= 3

Answer 2

Resposta:

$5(1 - x) - 2x + 1 = - 3(2 + x) \\ 5 - 5x - 2x + 1 = - 6 - 3x \\ - 5x - 2x + 3x = - 6 - 1 - 5 \\ - 7x + 3x = - 6 - 1 - 5 \\ - 4x = - 6 - 1 - 5 \\ - 4x = - 7 - 5 \\ - 4x = - 12 \\ x = - 12 \div ( - 4) \\ x = 3$
