Question

resolva as equaçoes


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


6(x-3)-2(2x-1)=3x


2x-6=-5x-20


3(T-5)+7T=5(3-7)

Answer 1

Explicação passo-a-passo:

-2+12+3×=6×-2

3×-6×=-2-12+2

-3×=-12(-1)

3x=12

×=12/3

×=4

6×-18-4×+2=3×

6x-4×-3×=-2+18

6×-7×=16

-×=16(-1)

×=-16

3t-15+7t=15-35

3t+7t=-35+15+25

10t=40-35

10t=5

t=5/10

t=0,5
