Which operation will cancel out division?
emmasim [6.3K]

Answer:

The operation that will cancel out division is multiplication.

Step-by-step explanation:

For example:

\frac{2+5x}{2} \\

*in order to solve for x, and get the upper equation without division, you must multiply by the negative reciprocal*

2*(\frac{2+5x}2} )

4+10x\\

*to get x alone, we must subtract 4 from both sides*

10x = -4\\\\-4 / 10 = - 2/5

x=- 2/5
