The y-coordinate of the solution s mathematically given as
y = 1.7
Generally, the equation is mathematically given as
5x + 2y = 7
10x + 4y = 14 .....1
-2x + 6y = 9
-10x + 30y = 45 .....2
Hence, solving further
10x-10x + 4y +30y = 14+45
0 + 34y = 59
y = 1.7
In conclusion, the y-coordinate of the solution.
y = 1.7
