Question

-14=-20y-7x 10y+4=2x

Answer 1

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
