2x+5x-11=10!
So once you combine like terms - 2x+5x, you end up with 7x-11=10
You then have to add 11 to both sides of the equal sign and you get 7x=21. If you divide both sides by 7, you end up with x=3.
Did you need what Y was, too ? If so, you just go back to the original problem:
2(3)+y=10
2 times 3 = 6+y=10.
Subtract 6 from both sides and you get Y=4!

3x - 5y = -35 <br> please solve and show your work
scoray [572]
You use the formula y=mx+b, therefore you have to isolate the y
First you subtract 3x to both sides.
3x - 5y = -35
-3x -3x
Then it would be
-5y = -3x -35
Then you divide -5 on both sides to isolate the y
-5y = -3x -35
/-5 /-5 /-5
Two negatives cancel out and make a positive so it would be
Y = 3/5x + 7
