Answer:
x = 5
Step-by-step explanation:
8x-9=7x+6-2x
We move all terms to the left:
8x-9-(7x+6-2x)=0
We add all the numbers together, and all the variables
8x-(5x+6)-9=0
We get rid of parentheses
8x-5x-6-9=0
We add all the numbers together, and all the variables
3x-15=0
We move all terms containing x to the left, all other terms to the right
3x=15
x=15/3
x = 5
