The first answer and the last one

Plug in each number into their designated spots.
Example with (0,5)

0 goes into x and 5 goes into the y variable and this is the equation now:

2*0 +4*5=20

0 times 2 = 0 and 4*5=20
So that is one of the correct answers.

Repeat the process and you find that the last option is also correct.

When solving for the system of linear equations by substitution what is the coordinate?
Oliga [24]

Answer:

x=-2, y=-9/2. (-2, -9/2).

Step-by-step explanation:

x=2y+7

3x-2y=3

--------------

3(2y+7)-2y=3

6y+21-2y=3

6y-2y+21=3

4y+21=3

4y=3-21

4y=-18

y=-18/4

simplify

y=-9/2

x=2(-9/2)+7

x=-9+7

x=-2
