Question 895001
x+2y=14
2y=x-10

Look at your question.

Let us solve x + 2y = 14 for x and then plug that into the other equation.

x = 14 - 2y.

See what I did?

We now plug this information into 2y = x -10.

2y = 14 - 2y

2y + 2y = 14

4y = 14

y = 14/4

How do you think we can find the value of x?

Select EITHER equation given, replace y with 14/4 and solve for x.

I'll let you do that.
