Question

Solve the system by using a table.
system
(1 point)

(–4, –3)
(–3, –4)
(4, 3)
(3, 4)

Answer 1

I need help solving for y please! :)

Answer 2

solve for 4x in the top equation and substitute that in to the second equation

Answer 3

I need to get two y=mx+ b equations, so i can graph them. i'm doing the equation wrong.

Answer 4

Oh sure, that's another way. Just solve for y in both equations then.
In the top one, divide by 3 on both sides.
In the bottom one, add 4x on both sides then divide by -4 on both sides.

Answer 5

Do you divide both the slope and b/y intercept by the -4 and 3?

Answer 6

for the 1st equation
3y= 4x+7
divide both sides by 3 (that means all terms are divided by 3)
\[ \frac{\cancel{3}y}{\cancel{3}}= \frac{4x+7}{3} \]
\[ y= \frac{4}{3}x + \frac{7}{3} \]

Answer 7

for the 2nd equation, first add +4x to both sides
then divide both sides by -4

Answer 8

That's what i got, but i started pluging number in to get one of the options, nothing worked...

Answer 9

could you please try plugging numbers in to find one of the options at the top? or give me numbers to plug in please?

Answer 10

ok, but first, what did you get for the 2nd equation?

Answer 11

y=-1x+7

Answer 12

how did you get that?

Answer 13

by adding -4x to the other side, then dividing by -4; y=4x+28/-4; y=-1+7

Answer 14

looks good except 28/-4 is not +7

you should get
y= -1x - 7

Answer 15

ahhhhhhhhhhhhhhhhhhhhhhhhh.

Answer 16

but how do i get one of the options above? like what numbers should i put in the equations????

Answer 17

you have 2 equations
y= (4/3)x + 7/3
and
y = -x -7

one way to find where they meet is sketch the lines to get an idea where they cross

or pick some numbers for x and find y

Answer 18

gahhhhhhhhhhhhhhhhhhhhh, i tried that, for some reason it's not workingg:(
