If the equation is structured like this:
(8/x)=(12/(x+2))
then x=4.
If the equation is structured like this: (8/x)=(12/x)+2 then x=-2.
72
3t + 7 = 2t - 5 3t = 2t - 12 t = -12
x+2(x+3) = 12 x+2x+6 = 12 x+2x = 12-6 3x = 6 x = 2 and y = 5
2x + 12 y =36subtract 2x from both sides12y = 36 - 2xdivide both sides by 12y = (36 - 2x)/12
2
12 + 5 equals...
b = 14
a= -0.8
-0.5
If n + 7 = 12, then n = 12 - 7
-12=m+4 -16=m
-3
1 over 3 plus 1 over 12 equals 5 over 12
7x = 3x - 12 4x=-12 x=-3
A + 9 = 21 A = 21 - 9 A = 12
X = 12
X=6
