X - 2y = -29 x - y = -11 first solve for x in the first equation; x = 2y - 29 now substitute it into the second equation; x - y = -11 2y - 29 - y = -11 y - 29 = -11 solve for y; y - 29 = -11 y = -11 + 29 y = 18 solve for x by substituting what y equals; x = 2y - 29 x = 2(18) - 29 x = 7 so your answer is, (7, 18) hope this helped!! blessings x
x-2y = -29
x-y = -11
we can solve for x in the second equation by adding y to both sides
x= -11 + y
now we can plug this in for the x value in the first equation to solve for y
-11 + y -2y = -29
-11-y=-29
-y= -18
y =18
now that we know what y is equal to, we can plug it in to either equation to solve for x
x-18= -11
x = 7
7 , 18
hope this helped
