x/9=12 multiply both sides by 9, giving x=108 ____________________________________________________________________ To solve the problem 'x over nine equals twelve', you must first recognize that any number over another number (which includes variables) is a division problem. Thus, all fractions are division problems. You have to multiply by the reciprocal, and multiplication is the opposite of division, and the reciprocal in this case would be 9/1, or just 9. You must apply this to both sides of the equation, so x/9 times 9 is x, and 12 times 9 is 108. Therefore, x =108.
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
Using the quadratic equation formula: x = 8.42 or x = -1.42
3t + 7 = 2t - 5 3t = 2t - 12 t = -12
1 + 12 = WHAT
b = 14
12/3 = 4
-0.5
You cannot solve this single equation. You can either change the subject so that it gives x = 12/y or xy = 12, which is the equation of a rectangular hyperbola.
X = 12
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.
12y = 132y = 132/12y = 11
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
Answer:12y=132y=132/12=11
the answer is-10 = 12 +xx= -10-12x=-22this is the answerx= -22
x=12
3n=36 Write the equation n=12 Divide each side of the equation by 3 to get the variable alone.
