The answer is D
Because if you replace the variables just by testing them they give the answer as X=-3 and Y=3.
In which replacing:
3(-3)+5(3)=6
and with the other equation we've got:
4(-3)+2(3)=-6
so they comply with the required to be the correct answer, even though you can make a system of equation.
Answer:
Multiply by 2 because if 6÷3=2, same for 24÷12=2
P = 2b + 2c...subtract 2b from both sides
P - 2b = 2c ...divide both sides by 2
(P - 2b) / 2 = c
P/2 - b = c <=== ur answer is D
You subtract 21 from 34, which leads you to -13 degrees F
