Question

olve each system of equations using substitution.

y = 1/2x + 4
2y + 2x = 2
Select one:
(3, 2)
(1, 3)
(3, 3)
(-2, 3)

Solve each system of equations using substitution.

x – y = 1
x = 1/2y + 2
Select one:
(2, 2)
(3, 0)
(3, 2)
(0, 2)

Answer 1

Ok, so for the first problem you need to plug in 1/2x + 4 for y in your second equation. Make sense?

Answer 2

kinda?

Answer 3

2(1/2x+4) + 2x = 2

Answer 4

Yes perfect. Now you need to distribute and solve for x.

Answer 5

OK @stardogchampion

Answer 6

And once you solve for x you need to plug that value back into the first equation to solve for your y value.

Answer 7

:O omg so many steps

Answer 8

Haha yeah. But don't worry, once you get the hang of this stuff it takes no time.

Answer 9

Oh ok thanks
