X + y = -1 4x - 2y = -16

djyliett [7]

Answer:

$x=-3 \\and\\ y=2$

Step-by-step explanation:

$x + y = -1$ Equation:1

$4x - 2y = -16$ Equation:2

Solving Equation:1

$x+y=-1$

Subtracting 'y' from both the sides:

$x+y-y=-1-y\\\\x=-1-y$

Putting 'x' in Equation :2

$4(-1-y)-2y=-16\\\\-4-4y-2y=-16\\\\-4-6y=-16$

Adding '4' both the sides

$-6y=-16+4\\\\-6y=-12\\\\y=-12/-6\\\\y=2$

Putting the value of 'y' in equation:1

$x+y=-1$

$x+(2)=-1\\\\x=-1-2\\\\x=-3\\$

The solution is:

$x=-3 \\and\\ y=2$
