Answer: x = 5.5 or 5 + 1/2
Explanation:
3(2x-5)-2x=7
We move all terms to the left:
3(2x-5)-2x-(7)=0
We add all the numbers together, and all the variables
-2x+3(2x-5)-7=0
We multiply parentheses
-2x+6x-15-7=0
We add all the numbers together, and all the variables
4x-22=0
We move all terms containing x to the left, all other terms to the right
4x=22
x=22/4
x=5+1/2
