Answer:
Explanation:
ok so first your going to do distributive property from left to right.
5 times 2x= 10x, 5 times 3= 15 so now the first part of the equation in 10x + 15 =
3 times 3x= 9x, 3 times 12= 36
so now its 10x+15=9x+36
now subtract 15 from the left side
and whatevr you do to one side you do to the other. The equation is now:
10x=9x+21
now subract 9x from 9x and from 10x
so now 1x=21
now divide by one so ur answer is x=21
