Answer:

x=5

Explanation:

you need to get the variable on one side and the constant on the other

So first, you need to simplify: 9x-8x would be x

so now you have x-3=7-x you need to add the x to both sides to get 2x-3=7 then you need to add the 3 to both sides.

now you have 2x=10

divide by 2 on both sides and you will get x=5
