Question

4x+3y=-5
x=y-3

Answer 1

Put the x value in the first equation!
And then solve! :D

Answer 2

,Where did you get the X value?

Answer 3

Do I solve
4x+3y=-5?

Answer 4

So to solve for that I would subsitute 3 for 0
4x=-5
-5/4=-1.25?

Answer 5

In the second equation :)
The x value is ALREADY given to you in TERMS of y!
So put it in the first equation as
4(y-3) + 3y = -5!
Expand the brackets and find the y value here! :D

Answer 6

So that gives me
4y-12+3y=-5

Answer 7

errr
4x-12+3y=-5

Answer 8

So 7y = 7
And y = 1
right? :D

Answer 9

Wait how did you get the 7?

Answer 10

Add 12 to both sides! :D

Answer 11

ok so adding 12 to both sides gives me
4x+3y=7

Answer 12

adding 4 &3 gives me 7y
7y=7
y=1

So that gives me
4y-12+3y=-5
YOU WROTE THIS RIGHT!! :D

Answer 14

YES!! :D

Answer 15

Gotcha! Thanks!

Answer 16

Okay so now!
AFTER GETTING THE y VALUE
Put it in the second equation [MORE CONVENIENT TAN FIRST]
And get the x value! :D

Answer 17

So I use y=1 in one of the original equations
x=1-3
1-3
x=-2

Answer 18

Thank you!

Answer 19

:) Good job! :)
