Question

Rewrite the equation below so it does not have fractions

Answer 1

Answer:  4x + 42 = 5

==========================================================

Explanation:

The fractions we want to eliminate are 2/3 and 5/6. The lowest common denominator (LCD) is 6.

If we multiply both sides by the LCD, then we'll cancel out the fractions. This is because

6*(2/3) = (6/1)*(2/3) = (6*2)/(1*3) = 12/3 = 4

6*(5/6) = (6/1)*(5/6) = (6*5)/(1*6) = 30/6 = 5

So in short, the (2/3)x becomes 4x and the 5/6 becomes 5 after we multiply both sides by the LCD 6.

This is what the steps could look like

$\frac{2}{3}x + 7 = \frac{5}{6}\\\\6*\left(\frac{2}{3}x + 7\right) = 6*\frac{5}{6}\\\\6*\left(\frac{2}{3}x\right) + 6*\left(7\right) = 6*\frac{5}{6}\\\\4x + 42 = 5$
