Question

Solve the following system.
y = x + 3
4x + y = 18

(6, 3)

(3, 6)

(−3, 6)

(3, −6)

Answer 1

So this problem is actually pretty easy.... do you have any idea where to start?

Answer 2

no

Answer 3

Why dont you start by plugging in the pints?
for example:
im going to use (6, 3)
(3) = (6) + 3
4(6) + (3) = 18
does that make any sense?

Answer 4

yes thank you

Answer 5

btw thats not the answer just saying.....

Answer 6

To solve this you can use substitution since this is a system you can substitute x+3 in for y
Does that make sense?

Answer 7

yeah

Answer 8

so then you can simplfy 4x+ x + 3 = 18 And what do you get?

Answer 9

3

Answer 10

Good job!!! so now that you know what x is you can plus that in to either of the 2 equations to finish the problem and find y

Answer 11

ok

Answer 12

So what did you get?

Answer 13

6

Answer 14

OKay good... see it wasn't hard at all

Answer 15

And this is random btw I love Snapback too..!!!

Answer 16
