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.
