Question

Solve by the substitution 3x-5y=-10
x=-3-2y type an ordered pair

Answer 1

Since you know what x is, put that in for x in the first equation.

Answer 2

3(-3-2y)-5y=-10
-9-6y-5y=-10
-11y=-1
y=1/11

Answer 3

by substituting -3-2y in place of x

Answer 4

3(-3-2y) - 5y = -10 (distribute)
-9 - 6y - 5y = -10
-11y - 9 = -10
-11y = -1
y = 1/11 (are you sure your problem is correct, teachers usually give you "nicer" answers. but I will continue)

Answer 5

x = -3 - 2y
x = -3 - 2(1/11)
x = -3 - 2/11
x = -3 2/11

Answer 6

so the orderd pair is a fraction?

Answer 7

(-3 2/11, 1/11)

Answer 8

wow, that's a pain to graph!

Answer 9

I wonder if the two equations are either entered correctly or there was a mistake in the problem... Teachers usually don't do this.

Answer 10

let me check , I'll be back in a minute.Thank you for your patience.

Answer 11

I checked, the real question was,"What is the solution to the system, type an ordered pair."
so all I need is the solution in coordinate terms

Answer 12

OK.. so (-3 2/11, 1/11)

Answer 13

it appears your right

Answer 14

thanks
