Question

Given the following system of equations, solve it by using substitution and elimination. Do

you get the same answer? Why or why not? Explain using complete sentences.
2x+3y = -14
3x + y =-14

Answer 1

Explanation:

2x+3y=-14------equation i ×1

3x+y=-14--------equation ii ×3

2x+3y=-14

9x+3y=-42

-7x =- 28

x=4

Substitute for x in equation ii

3x+y= -14

3(4)+y=-14

12+y=-14

y=-14-12

y=- 26
