Complete question :

Use this system of equations to answer the questions that what number would you multiply the second equation by in order to eliminate the x-terms when adding to the first equation?

What number would you multiply the second equation by in order to eliminate the y-terms when adding to the first equation?

4x – 9y = 7

–2x + 3y = 4

2 ; 3

Step-by-step explanation:

Given the equations :

4x – 9y = 7 - - - - - (1)

–2x + 3y = 4 - - - (2)

The number to multiply equation (2) by in other to eliminate the x-term :

We multiply equation (2) by 2 ; thus we have ;

4x - 9y = 7 - - - - (1)

-4x + 6y = 8 - - - - (2) ; adding (1) and (2)

- 3y = 15

The number to multiply equation (2) by in other to eliminate the y-term :

We multiply equation (2) by 3 ; thus we have ;

4x - 9y = 7 - - - - (1)

-6x + 9y = 12 - - - - (2) ; adding (1) and (2)

-2x = 19

one of each metals

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
