Let the variable be x:
12/x = 6/7
Multiply both sides by x:
12 = 6x/7
Multiply both sides by 7:
84 = 6x
Divide both sides by 6 to find the value of x:
x = 14
m-12=25. m=37
x=12

1/6=x/12 12=6x 2=x
You add 12... r + (-12) = 19 r + (-12) + 12 = 19 + 12 r = 31
3n=36 Write the equation n=12 Divide each side of the equation by 3 to get the variable alone.

-6 = x/8+4. Work out the same values first, in this case it is the 8 + 4, which equals 12. -6 = x/12 Move the number next to the variable, in this case the x, over the other side of the equals sign, but remember that as you are doing this you MUST change the sign to the opposite. Since x/12 equals x over 12, it means it is x divided by 12. When moved over the equals sign, it WILL become a multiplication sign. -6 x 12 = x -72 = x x = -72.

12 + 5 equals...
b = 14

11 times 12 = 132
