Answer:

2

Explanation:

we can isolate the variable by subtracting 3x from both sides

3x + 12 = 5x + 8

-3x -3x

12 = 2x + 8

and then subtracting 8 from both sides

12 = 2x + 8

-8 -8

4 = 2x

then we divide by 2 on both sides

4 = 2x

÷2 ÷2

2 = x

flip the equation to get:

x=2

checking the solution by plugging in 2 in place of x:

(3 * 2) + 12 = (5 * 2) + 8

6 + 12 = 10 + 8

18 = 18

since the equation is true,

the solution x = 2 is correct.
