Question 163264
I am assuming you just need to solve for x, so here goes:
Multiply each side out by distributing the 3 and the 5, respectively, to get:
3x + 18 = 5x -20
Now, get the x's on one side and the constants (numbers without variables) on the other side:
You do this by first subtracting 3x from each side, to get:
18 = 2x - 20
Now, get rid of the constant on the right hand side by adding 20 to both sides, to get:
38 = 2x
Now, since x is multiplied by 2, you  must divide both sides by 2 to get x by itself.  This gives you:
19 = x, which is your answer.

That's it!  You can do this!
Good luck!
