Answer this using a graphing method!

Step-by-step explanation:

5x-2y=10

x-y=-1

Addition method

multiply the second equation by -2 and add it to the first one

5x-2y=10

-2x+2y=2

Total 3x=12

Divide by sides by 3

x=4

Now multiply the second equation by -5 and add it to the first one

5x-2y=10

-5x+5y=5

3y=15

Divide both sides by 3

y=5

Solutions are x=4 and y=5

2nd method

if x-y=-1, so x=y-1

bring the value of x in the first equation

5(y-1)-2y=10

5y-5-2y=10

put the similar term together

3y=15

Divide both sides by 3

y=5

now bring the value of y in one of the equation

x-y=-1

so x-(5)=-1

x=-1+5

x=4

Solutions are x=4; y=5

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
