Hello there!

2(3x - 4) + 10 = 5(x + 4)
First, let's distribute 2 to 3x and -4, then 5 to x and 4.
2(3x) + 2(-4) + 10
6x - 8 + 10
6x + 2 is our first half of the equation simplified. Now let's do the other.

5(x + 4)
5(x) + 5(4)
5x + 20 is our second half of the equation simplified. Now let's put them back in their original spots.

6x + 2 = 5x + 20
Get x on one side - subtract 5x from both sides.
x  + 2 = 20
Isolate x by adding 8 to both sides.
x = 18 is our answer.

I hope this helps!
