Question

Resolva a equação

A) 3-2 (x + 3) = × -18

B) 8x -12 = 23 - 4x​

Answer 1

3 - 2(x + 3)= x - 18

3 - 2x - 6= x - 18

- 2x - x= - 18 - 3 + 6

- 3x= - 15>>.(-1)

3x= 15

x= 15/3

x= 5

_________________

8x - 12= 23 - 4x

8x + 4x= 23 + 12

12x= 35

x= 35/12

Answer 2

A) 3-2x-6=x-18

-2x-x=--3+6-18

-3x=-15

x=-15/-3

X=5

B) 8x+4x=12+23

12x=35

x=35/12
