If x + 2y = 8, and x - y = 5, what is the value of x?

x = 6

Step-by-step explanation:

Let's solve y for x + 2y = 8.

x + 2y = 8

2y = -x + 8

y = x + 4.

Let's solve y for x - y = 5.

x - y = 5

y = x - 5

Since both equations have been solved for y, we can combine them together into one!

x - 5 = x + 4

x x = 4 + 5

1.5x = 9

x = 6

Hope this helped! If not, please let me know!

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
