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.

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
1 over 3 plus 1 over 12 equals 5 over 12
If n + 7 = 12, then n = 12 - 7
-12=m+4 -16=m
7x = 3x - 12 4x=-12 x=-3
X = 12
A + 9 = 21 A = 21 - 9 A = 12
X=6
5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.
