3(x+2)=-x-6


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

Answer 1

3(x + 2)= - x - 6

3x + 6= - x - 6

3x + x= - 6 - 6

4x= - 12

x= - 12/4

x= - 3

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

4x - 4= 2x + 6

4x - 2x= 6 + 4

2x= 10

x= 10/2

x= 5

Answer 2

Oie, Td Bom?!

I.

3(x + 2) = - x - 6

3x + 6 = - x - 6

3x + x = - 6 - 6

4x = - 12

x = - 12/4

x = - 3

II.

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

4x - 4 = 2x + 6

4x - 2x = 6 + 4

2x = 10

x = 10/2

x = 5
