Collect like terms
x + 4x - 4 = 9 - 2 x - 6
move the terms
5x - 4 = 3 - 2x
collect like terms calculate
5x + 2x = 3 + 4
7x = 7
answer is x = 1
-2x+8 = x-1 substitute for one of the y
-8. -8 solve for x
-2x = x -9
+x =. +x
-1x = -9
/-1. =. /-1
x=9
y=-2(9)+8 now solve for y by putting x
y= 18 +8 in the one of the original
y= 26 equations.
(9,26)
X=11,-1 is the right answer
Find a common denominator first
2 24/40 - 1 15/40 = 1 9/40
it is already in simplest form so you can not reduce it
