Question

Solve the following system of equations enter the y coordinate of the solution.5x+2y=7 -2x+6y=9

Answer 1

Hey Welsh.

Hint solve either by substitution method or elimination

Answer 2

use elimination

5x + 2y = 7 multiply this by -3
-15x - 6y = -21 ----- (1)
-2x + 6y = 9 ------- (2)

adding
-17x = -12

now find x
then you can find y by plugging in this value for x into the first equation and solving for y
