If the equation is let's say 3x+ 7 +4x to combine like terms, you would take 3x and 4x since they both have x. You wouldn't take the 7 since it doesn't have and x like the other numbers. 3x +4x = 7x so your new equation would be 7x + 7.
Y = 1 and x = 10
To solve this you cancel out the x's and get -8y=-8.
You find y as 1, plug it back into the equation to get 2x-5=15. Solve and get x=10.
