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

Equation P: y + z = 6
Equation Q: 3y + 4z = 1

Which of the following is a possible step used in eliminating the y-term?

(y + z = 6) • 4
(3y + 4z = 1) • 4
(y + z = 6) • –3
(3y + 4z = 1) • 3

who writes this nonsense?

anonymous · Answer

if you multiply the first equation by $-3$ you will get $-3y$ so when you add to the second equation the y terms will add up to zero 
go with 
(y + z = 6) • –3
