Question

4. Solve the system using elimination. (1 point)

3x +2y =17
2x+5y = 26
O (3,4)
0 (17)

Answer 1

Explanation:

Multiply the first by -2

Multiply the second by 3

so the x variable can be cancelled,eliminated

3x +2y =17

2x+5y = 26

-6x - 4y = -34

6x +15y = 78

11y = 44

y=4

Now plug this value to get x

3x+8 = 17

3x = 9

x=3

The answer (3,4)
