(8, –22)

Answer 1

@Mehek14 do you know to do this?

Answer 2

yes I do :]

Answer 3

ok :)

Answer 4

put the value of y in the second equation for y in the first equation
\(\bf{-2x-6=-4x+10}\)

Answer 5

ok

Answer 6

now solve for x

Answer 7

so the -2x-6=-4x+10 is how u add y in the second equation to the first?

Answer 8

I put the second equation for y in the first equation

Answer 9

so solve for x

Answer 10

6?

Answer 11

my ad
\(\bf{-16=-2x}\)

Answer 12

ohh ok

Answer 13

I forgot how to do it, thanku

Answer 14

now can you do the last step?

Answer 15

what is the next step?

Answer 16

how can you solve for x?

Answer 17

multiply something?

Answer 18

divide -16/-2 = x

Answer 19

-8

Answer 20

negative/negative = positive

Answer 21

so +8

Answer 22
