Question

Solve the following system of equations. Enter the y-coordinate of the solution. Round your answer to the nearest tenth 5x+2y=7 -2x+6y=9 is it (0.7,1.7)??

Answer 1

I got a 2 fractions for the answer the first is 12/17 and the second is 59/34 

Answer 2

5x + 2y = 7....multiply by 2
-2x + 6y = 9 ....multiply by 5
---------------
10x + 4y = 14 (result of multiplying by 2)
-10x + 30y = 45 (result of multiplying by 5)
--------------add
34y = 59
y = 59/34 = 1.7 <===
