A merchant has coffee worth $20.00 per pound that she wishes to mix with 70 pounds of coffee with $90.00 per pound to get a mix

Crank

20x-1000 +4000 = 60x

20x-60x= -4000 +1000

-40x= -3000

x= -3000/-40

75 The mix will be 75 lbs

And $20 coffee will be 75 -50 = 25lbs

Can someone please help me with 5 and 6(Best answer = Brainliest)

Alex_Xolod [135]

5.
First plug the value of x into the equation
$2(-2y-12)+y=9$
then solve for y
$2(-2y)+2(-12)+y=9 \\ -4y+(-24)+y=9 \\ -4y-24+y=9 \\ -3y-24=9 \\ -3y=33 \\ \frac{-3y}{-3}= \frac{33}{-3} \\ y = -11$

6. Do the same steps
$5(-y-1)+y=-13 \\ 5(-y)+5(-1)+y=13 \\ -5y+(-5)+y=13 \\ -5y-5+y=13 \\ -4y-5=13 \\ -4y=18 \\ \frac{-4y}{-4}= \frac{18}{-4} \\ y=-4.5$
