Answer: x = 2.5
Step-by-step explanation: To solve this equation, we start by distributing the 3 through the parenthses on the left side.
So we have 3(2x) which is 6x and 3(-3) which is -9.
So our equation now reads 6x - 9 = 6.
Solving from here, we need to isolate the term containing x which is 6x.
Since 9 is being subtracted from 6x, we add
9 to both sides of the equation to isolate the 6x.
On the left, the -9 and +9 cancel out and on the right, 6 + 9 is 15.
So we have 6x = 15.
Now we can finish things off by just
dividing both sides of the equation by 6.
On the left the 3's cancel and on the right, 15 divide by 6 is 2.5.
So x = 2.5.
