Question

2x+3y=11
5x+3y=15
What is the answer ?

Answer 1

x = 1 1/3 and y = 2 7/9

Explanation:

Subtract the two equations:

`5x + 3y = 15\\2x + 3y = 11`

3x = 4

divide both sides by 3

x = 4/3

Substitute this into the equation 5x + 3y = 15

`5((4)/(3) ) + 3y = 15\\(20)/(3) + 3y = 15\\3y = 8(1)/(3) \\y = 2(7)/(9)`

Answer 2

(X,Y)=(
`(4)/(3)` ,
`(25)/(9)`)
