Question

What is the solution to the system of equations?

y = 2/3x + 3
x =-2

[-2, -15/2 ]
[-2, 5/3]
(-2, 11/6
(-2, 13/3)

Answer 1

(- 2,
`(5)/(3)` )

Explanation:

y =
`(2)/(3)` x + 3 → (1)

x = - 2

substitute x = - 2 into (1)

y =
`(2)/(3)` × - 2 + 3 = -
`(4)/(3)` +
`(9)/(3)` =
`(5)/(3)`

solution is (- 2,
`(5)/(3)` )
