Answer:
x = 4y - 5
Explanation:
Solve for x means to get the x all by itself on one side of the equation.
Sometimes it is a number answer, but since you don't know y in this question, you are going to get an equation for your answer.
2x + 10 = 8y
Subtract 10 from both sides.
2x = 8y - 10
Divide both sides by 2.
x = (8y - 10)/2
This can be your answer, where the right side is a big fraction with 8y -10 on top and 2 on the bottom. Or you can try to simplify more:
x = 8y/2 - 10/2 by separating the /2 to be under the 8y and the -10 separately. Because then you can simplify a little bit more.
x = 4y -5
