Question

2x+5y=16 3x-5y=-1 solve by linear equations by elimination

Answer 1

(3, 2)

Explanation:

Rewrite the two equations, one above the other:

2x+5y=16

3x-5y=-1

If we now add the two equations together, we eliminate y and end up with 5x = 15. Then x must be 3. Substituting 3 for x in the first equation, we get 2(3) + 5y = 16

or 5y = 10. Then y = 2, and the solution to this system is (3, 2)
