Answer: x = 1/3
Step-by-step explanation: Start by changing the -3 to plus a negative 3 so you know that you are distributing a -3 through the parentheses.
-3(5x) is -15x and -3(-2) is 6.
So we have 8x - 15x + 6 = 7 - 10x.
Simplifying the left side further gives us -7x + 6 = 7 - 10x.
Now subtract 6 from both sides to get -7x = 1 - 10x.
Now add 10x to both sides to get 3x = 1.
From here it should be easy to find that x = 1/3.
