Question

Which ordered pair is a solution to the system of equations?
y=3x
Y= 2x +3

Answer 1

Answer:

(3, 9 )

Step-by-step explanation:

y = 3x → (1)

y = 2x + 3 → (2)

Substitute y = 3x into (2)

3x = 2x + 3 ( subtract 2x from both sides )

x = 3

Substitute x = 3 into (1)

y = 3 × 3 = 9

solution is (3, 9 )
