Question

What is the solution to the system of equations?

y = 1.5x – 4

y = –x

(–1.6, 1.6)
(–1.5, 1.5)
(1.5, –1.5)
(1.6, –1.6)

Answer 1

Set them equal to each other. Solve for x than plug that back in and solve for y

Answer 2

wym?

Answer 3

first step is -x=1.5x-4

Answer 4

Than solve for x

Answer 5

once u solve for x, plug that into the x variable to find y.

Answer 6

so do i subtracy 4

Answer 7

You want to get x on one side first

Answer 8

and then get the numbers without x on the otherside

Answer 9

So for ex:
-x=1.5x-4
Start by adding x and 4 to both sides.
So that 2.5x=4.
Then you can divide by 2.5 to get the value of x

Answer 10

Once you find that plug that into any of the equations to solve for y

Answer 11

what coordinate did you get?

Answer 12

i got -1.5 again

Answer 13

for x or y?

Answer 14

x

Answer 15

what is 4/2.5?

Answer 16

That would be your x-coor.

Answer 17

shouldn't be -1.5

Answer 18

1.6

Answer 19

correct

Answer 20

for x?

Answer 21

Put back in any of the equations to find the y-coor of the solution

Answer 22

yes for x

Answer 23

Yes that is for x!!!

Answer 24

so d?

Answer 25

yep

Answer 26

thanks guys

Answer 27

what one only has 1.6 as x?

Answer 28

so yes. ur right.
