Question

Use substitution to determine which system is represented by the graph.
A) 2x+4y=28
-2y=x+28
B) 2y=2x+5
3x-4y=-5
C) y = 3 x +10
2x-3y=10
D) y=10x-15
-9x+2y=10

Answer 1

Answer:

A. because its determine which system is graph

Answer 2

Answer:

First I solve the ques D

Step-by-step explanation:

y=10x-15

2y-9x=10

we take the value y in the above equation

and put in the below equation

2y-9x=10

2(10x-15)=10

20x-30=10

20x=10+30

20x=40

x=40/20

x=2

Now we have x value

we put it in the equation y=10x-15

y=10(2)-15

y=20-15

y=5

Now we have both values

x=2 and y=5

I will hope

this help you !!!

Now u solve the the other question and make the graph
