It should be,
4x-8=2x-10 because you substitute that for y.
Now you do,
4x-2x because you do the opposite of the positive 2x as you bring it to the other side.
That is,
2x-8=10 now you bring the 8 to the other side.
2x=10+8 I added it because I do the opposite and it is a negative 8 so I add.
2x+18 now divide
x=9 that's the answer.
Answer:

Isolate the variable by dividing each side by factors that don't contain the variable.
4/10= 8/20, 2/5. For 8/20 u multiply 2 times and for 2/5 u divide by 2
Hope that helps u
