Answer:
x=8
Step-by-step explanation:
We first simplify both sides of the equation so it turns out like this:
(5x+x) + (3+4) =55
6x+7=55
Then we subtract 7 from both sides:
6x+7-7=55-7
6x=48
From there we divide both sides by 6:
6x/6=48/6
x=8
The answer would be 2a-7 because a negative times a negative is a postive so -(-2a) is 2a and negative times a postive is a negative so -(7) is -7
