Question

Which ordered pair is the solution to the system of equations? {y=3x−10

2x+3y=3
(2, 4)
(3, −1)
(4, −2)
(0, 1)

Answer 1

(3,-1).  You can know the answer by plugging in the x and y values into the equations and it is a solution if both are true.

Answer 2

Answer: (3,-1)

Step-by-step explanation: y=3x-10 and 2x+3y=3

putting y=3x-10 in 2x+3y=3

⇒ 2x+3(3x-10)=3

⇒ 2x+9x-30=3

⇒ 11x=33

⇒ x=33/11

⇒ x=3

Putting x=3 in y=3x-10 ,we get

y=3×3-10

⇒ y=9-10

⇒ y=-1
