Answer:
C multiply the first equation by 3
Step-by-step explanation:
3x-y =5
2x+3y = 10
We want to eliminate y
Since the first equation has a negative 1y and the second equation has 3y
I would multiply the first equation by 3 and then the y's cancel
3(3x-y =5)
9x -3y = 15
2x+3y = 10
------------------
11x = 25
5 (4x2) + 6 - (2x2) - 1
5 + 6 = 11, 4 x 2 = 8
2 x 2 = 4, 11 + 6 = 17
17 - 1 = 16
