(15points) me with this i really need

Solve each equation separately:

(-1, 3) Has to be a point that fits both equations

y = 2x +

Plug in Values:

3 = 2(-1) +

3 = -2 +

___ = 5

First Blank: 5

y = ___x - 1

Plug in Values:

3 = ___(-1) - 1

4 = ___(-1)

___ = -4

Second Blank: -4

the first one you plug in 3 for y and -1 for x:

3=2(-1)+? plug in x&y coordinates

3= -2 +? multiply -1×2

5 = ? add 2 to both sides

the second one you do the same:

3=?(-1)-1 plug in x&y coordinates

4=?(-1) add 1 to both sides

-4=? divide by -1

answer: for each 3 girls there is 2 boys . 3: 2

hope this ! (:   mark me as brainliest if you can

go and ask your mom to you
