The two given equations are:
-14=-20y-7x and 10y+4=2x
In order to find x and y, we can do it by substitution or by elimination.
By Elimination.
Multiply 10y+4=2x by 2
= 20y + 8 = 4x
Then add it to the second equation
-20y - 7x = -14
20y - 4x = -8
---------------------
-11x = -22
x = 2
Then get y,
10y+4=2x
10y = 2x - 4
10y = 2(2) - 4
y = 0.
So the answer is x = 2, y = 0
