Question

What is the solution set of the following system of equations?

5x - 3y - 10 = 0
x + y - 7 = 0

{(31/8, 25/8)}
{(25/8, 31/8)}
{(45/2, 31/2)}
{(31/2, 45/2)}

Answer 1

i got {(31/8, 25/8)}

Answer 2

same @hhelpplzzzz

Answer 3

5x - 3y = 10
x + y = 7

-5x - 5 y = - 35
5 x - 3y = 10

-8y = -25
y = 25/8

x = 7 - 25/8= 31/8

You're correct.

Answer 4

thank you:)

Answer 5

well - you can easily check your own answer

you should get into habit of doing this

just put the values you got into both equations and see if the equations are true
