Solve the system using elimination 3x+2y=17 and 2x+5y=26
Arte-miy333 [17]

Answer:

3x + 2y = 17

2x + 5 y = 26

Step-by-step explanation:

3x + 2y = 17 }

2x + 5 y = 26}

x - 3y = - 9

x = -9 + 3y

=> 2 (-9+3y)+5y=26

-18+6y+5y=26

-18+11y=26

11y=26+18

11y=44

y= 4

3x + 8=17

3x = 17 - 8

3x = 9

x = 9 : 3

x = 3
