Ivanshal [37]

Answer:

For the first equation the answer for "X" will be,

$x = \frac{ - 4 - y}{2}$

if you want me to solve for y instead then the answer will be,

$y = - 4 - 2x$

for the second equation the answer for "X" will be,

$x = \frac{1 + 3y}{5}$

If you want me to solve for y instead then the answer will be,

$y = - \frac{1 - 5x}{3}$
