-5x + 13 = -12 -5x = -12 - 13 = -25 x = -25/-5 = 5
5+x=x+5 is an example of the commutative property of addition.
(8 + 4) x 5...
the Y in the sentence X plus Y equals 5 is Y=3 or 2 if the X is 2 or 3
X=6
no...why would it.... it equals 2x+9
so 3x + 2 = x + 12 ie 2x = 10 x =5
5=4x 1.25=x
x = 11/7 and y = 12/7
x=5
3 - 8 + 12 = x -5 + 12 = x 7 = x Answer : 7
7
(5, 1)
2x+12-3x = 5 2x-3x = 5-12 -x = -7 x = 7
-13 Plug 5 in and multiply it by -5 which equals -25 12 - 25 = -13
X=5/12
