Never use x to represent multiplication in algebra because it gets confused with the variable x.

I will assume that you meant to type

-9 times (5 - 2x).

Answer: -45 + 18x.

If you meant to type -9x(5 - 2x), then the answer is -45x + 18x^2.

Minchanka [31]

-3/2 is the  factor would multiply the second equation to eliminate y.

The correct option is (C).

<h3>What is factor?</h3>

A number or algebraic expression that divides another number or expression evenly—i.e., with no remainder.

Given equation is :

9x+3/4 y =6

2x+1/2 y =9

If we have to eliminate the y variable so we have to multiply it by factor -3/2

Then the second equation become

-3/2(2x+1/2 y =9)

-3x- 3/4 y =- 27/2

As we can see the y variable of both the equation is same.

Hence, -3/2 is the  factor would multiply the second equation to eliminate y.
