Best Answer

(x + 10)/2 = (x - 6)/x.

Multiply both sides by 2x to produce:

x2 + 10x = 2x - 12

Rearrange and collect like terms to produce:

x2 + 8x + 12 = 0

Factoring produces:

(x + 6)(x + 2) = 0, which is true whenever x = -6 or x = -2

Check: for x - -6: (-6 + 10)/2 = 2; (-6 - 6)/-6 = -12/-6 = 2

(-2 + 10)2 = 4; (-2 - 6)/-2 = -8/-2 = 4.

What is 3 eith of 56?

To do this, you have to cross multiply. (It helps if you write this down on paper as you read). So, 3 over 8 = n (unknown number) over 56. Then you use a trick called cross multiplication. You just multiply the numbers diagonal from each other and your equation equals 3x56=8n. Get it? When you multiply 3 and 56, you get 168=8n. From here, you divide both sides by 8 to get what n equals. 168/8=8n/8. When you divide 168 and 8, you get 21. So, n=21. 3 eighths of 56 equals 21! :)

When do you cross multiply in dividing fractions?

To divide fractions, turn the second one over - that is, swap its numerator and denominator - and multiply. Nothing else is necessary. You cross multiply when you have a proportion, that is when you have two ratios that are equal.
