Q:
Solve the system of equation. 5x+2y=7 and -2x+6y=9. Enter the y-coordinate of the solution.
Accepted Solution
A:
Answer: [tex]\bold{y=\dfrac{59}{34}}[/tex]Step-by-step explanation: 5x + 2y = 7 ⇒ 2(5x + 2y = 7) ⇒ 10x + 4y = 14 -2x + 6y = 9 ⇒ 5(-2x + 6y = 9) ⇒ -10x + 30y = 45 34y = 59 ÷34 ÷34 y = 59/34
