Question

encontre a solução da equação do 1 grau 5(3-x)+2(x+1)=-x+5

Answer 1

5 (3 - x) + 2(x + 1) = - x + 5
15 - 5x + 2x + 2 = - x + 5
17 - 3x = - x + 5
17 - 5 = - x + 3x
12 = 2x
2x = 12
x = 12/2
x = 6

Answer 2

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

$(15-5x)+(2x+2)=-x+5$

$2x-5x +15+2=-x+5$

$-3x +17=-x+5$

$-3x+x =5-17$

$-2x =-12$

$x= \frac{-12}{-2}$

$x = 6$
