<span>3x – 4y = 21
</span>3(-3) - 4(3) = 21
-21 = 21 >>>>> not equal
B. (−1, −6)
<span>3(-1) - 4(-6) = 21
</span>21 = 21 >>>>>>>>>>Equal
C. (7, 0)
<span>3(7) - 4(0) = 21
</span>21 = 21>>>>>>>>>>equal
D. (11, 3)
<span>3(11) - 4(3) = 21
</span>21 = 21 >>>>>>>>>equal

Answer:
The amount of peanuts to use is 5 pounds and that of cashews is 30 pounds.
Step-by-step explanation:
Let the amount of peanut to use to be x
Let the amount of cashews to use to be 35-x
Form equations to compare amounts for individual foods and the mixture

So the pounds to be used for peanuts is 5 pounds
The pounds to be used for cashews will be 35-x= 35-5=30 pounds
