What is the answer to 7 over x plus 3 over 4 equals 5 over x?
7/x + 3/4 = 5/xMultiply through by 4x: 7*4 + 3*x = 5*4or 28 + 3x = 20Subtract 28 from both sides: 3x = -8Divide both sides by 3: x = -8/37/x + 3/4 = 5/xMultiply through by 4x: 7*4 + 3*x = 5*4or 28 + 3x = 20Subtract 28 from both sides: 3x = -8Divide both sides by 3: x = -8/37/x + 3/4 = 5/xMultiply through by 4x: 7*4 + 3*x = 5*4or 28 + 3x = 20Subtract 28 from both sides: 3x = -8Divide both sides by 3: x = -8/37/x + 3/4 = 5/xMultiply through by 4x: 7*4 + 3*x = 5*4or 28 + 3x = 20Subtract 28 from both sides: 3x = -8Divide both sides by 3: x = -8/3
What are the first ten multiples of 28?

The difference of a number and 9 is 37 less the number find the number?
|x-9| = 37-x Suppose x-9 < 0 then 9-x = 37-x which is inconsistent. So 9-x > 0. Then x-9 = 37-x Add x to both sides: 2x-9 = 37 Add 9 to both sides: 2x = 46 so that x = 23.
What two numbers equal negative 28 when multiplied?
Combinations of such integers are: 1 x (-28) = 28 2 x (-14) = 28 7 x (-4) = 28 14 x (-2) = 28 (-1) x 28 = 28 (-2) x 14 = 28 (-7) x 4 = 28 (-14) x 2 = 28
