-2x+13y=11 13y=2x+11 y=2x/13 + 11/13
13=e+2 11=e (subtract 2 from each side)
5
X +13 equals 22, X equals nine
12 + 5 equals...
-11
-13 + 24 = 11
4r + 13 = 57subtract 13 from both sides:4r + 13 - 13 = 57 -134r = 44divide both sides by 4 to solve for r:4r/4 = 44/4r = 11
To solve for x, we'd have to know what this expression equals.
basically you asked what -28+21 which equals -7
13=m+2m=11
If: 2a+13 = 5a+1 Then: a = 4
