Answer:
Step-by-step explanation:
First we need to solve x + 3y = -18 and 5x + 2y = 14.
[tex]x = -18 - 3y[/tex].
Putting the above value in the second equation, we get, [tex]5x + 2y = 14\\5(-18 - 3y) + 2y = 14\\-90 -15y - 2y = 14\\17y = - 104\\y = - \frac{104}{17} = 6.2[/tex].
Hence, [tex]x = -18 - 3y = -18 -3\times\frac{104}{17} = -36.353[/tex]
