Question

(pre algebra) i medal and fan question is below

Answer 1

A student is trying to solve the system of two equations given below:

Equation P: a + b = 6
Equation Q: 4a + 2b = 19

Which of the following steps can be used to eliminate the a term?

−1(4a + 2b = 19)
−4(4a + 2b = 19)
−4(a + b = 6)
4(a + b = 6)

Answer 2

so if we wanted to cancel the terms, we would try to get the smaller term to be a negative form of the bigger one
we have the terms
a and b and
4a and 2b
to cancel the b's we would have to multiply b by -2
to cancel the a's we would have to multiply the a's by -4
to keep the truth of the sentence, we have to do that to the whole equation

so we see that there is no multiplying by -2 but there is multiplying by -4 so that is the answer

the one that is : -4(a+b=6) is the answer

Answer 3

does that help

Answer 4

i need someone to explain how i would solve this so i can know how to solve this in the future

Answer 5

the anwers i correct

Answer 6
