Examine this system of equations. Which number can be multiplied by each equation so that when the two equations are
andreyandreev [35.5K]

Answer:

15 times the first equation and -12 times the second equation

Step-by-step explanation:

we have

\frac{3}{4}x+\frac{2}{3}y=6 ------> first equation

\frac{5}{8}x+\frac{5}{6}y=12 ------> second equation

Multiply the first equation by 15 both sides

(15)\frac{3}{4}x+(15)\frac{2}{3}y=6(15)

\frac{45}{4}x+10y=90 -----> new first equation

Multiply the second equation by -12 both sides

(-12)\frac{5}{8}x+(-12)\frac{5}{6}y=12(-12)

-\frac{60}{8}x-10y=-144 -----> new second equation

Adds the two new equations

\frac{45}{4}x+10y=90\\-\frac{60}{8}x-10y=-144\\-----------\\\frac{45}{4}x-\frac{60}{8}x=90-144

The y-term was eliminated
