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*

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

$x=- 2/5$

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).

Answer:

The solution of this system of equations is (3 , -8)

Step-by-step explanation:

The given system is

x + 2y = -13

12x + 5y = -4

We make x the subject of the first equation and put it into the second:

$x = - 13 - 2y$

We put this expression for x into the second equation

12(-13-2y)+5y=-4

-156-24y+5y=-4

-24y+5y=-4+156

-19y=152

y=-8

We substitute y=-8 into x=-13-2y to get:

$x = - 13 - 2( - 8) = 3$

The solution of this system of equations is (3 , -8)
