Question

Solve the system of equations
2x+4y=16
2x-4y=0

Answer 1

add the equations..you end up with

4x = 16

divide both sides by 4

x = 4

got that?

Answer 2

now sub in 4 into an x of any of the two equations then solve for y

Answer 3

so is it (4,2) as an ordered pair

Answer 4

no...like i said sub 4 into an x of any equation..let's say first equation...i'll substitute 4 into the x of the first equation

2y + 4x = 16

2y + 4(4) = 16

2y + 16 = 16

are you seeing the value of y now?

Answer 5

you're right isabellayoung98, it's (4,2)
