You can put this solution on YOUR website! hey,
So for this one we need to just use algebra:
3(x-7) = -3
So first we use distribution with the parenthesis
Note: you always start with parenthesis:
3(x) - 3(7) = -3
Then:
3x - 21 = -3
Then we want x all by itself on one side, so we add 21 to both sides to get rid of -21 on the left side:
3x - 21 + 21 = -3 +21
3x = 18
Now, we divide each side by 3 to get rid of the 3 on the left side, so x will be alone:
3x/3 = 18/3
And we get:
x = 6
I hope this helps!
