Question

2X - ye42=x+y=-11ソチ4

Answer 1

Solution

We have the following system of equations:

1/2 x -1/4 y = 2 (1)

x + 1/4 y = -1 (2)

We can solve for x from the first equation and we got:

x= -1 -1/4 y (3)

Replacing (3) into (1) we got:

$\frac{1}{2}(-1-\frac{1}{4}y)-\frac{1}{4}y=2$$-\frac{1}{2}-\frac{1}{8}y-\frac{1}{4}y=2$

Solving for y we got:

$-\frac{3}{8}y=\frac{5}{2}$

y= -20/3

And x would be:

x= 2/3
