Question

resolva os seguintes equação
$5(x + 2) - 13 = 2(3x - 1)$


$7(2 + x) = 5(x - 1) = - (x + 5)$



$3(x + 1) - 2(x - 1) = - (x + 5)$
​

Answer 1

a) 5x+2-13=6x-3

5x-6x=-3-2+13

-x=8

-x=8 .(-1)

x=-8

b)14+7x=5x-5=-(x+5)

7x-5x-x=5-14+5

13x=-4

x=-4/13

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

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

3x-2x-x=5-2+3

x=6

Espero ter ajudado

Bons estudos
