Given the equations 9x+3/4y=6 and 2x+1/2y=9, by what factor the equation to eliminate y and solve the system through linea would you multiply the second equation to eliminate y and solve the system through linear combinations?

options;
a.) -4/3
b.) -3/4
c.) -3/2
d.) -7/2

C is correct.

Step-by-step explanation:

Given: System of equation

We have to solve system of equation by eliminating y

So, first we will make the coefficient of y same with opposite sign.

Coefficient of y in first equation 3/4

Coefficient of y in 2nd equation 1/2

Multiply second equation by -3/2 to make coefficient of y same

Add both equation and eliminate y

Hence, We multiply by -3/2 to eliminate y and solve the system of equation.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

the answer is a
