A)<br> 2x + y - 12 = 0<br> x + y + 3 = 0

Answer:

x=15 and y= -18

Step-by-step explanation:

$2x + y - 12 = 0$ Equation 1

$x + y + 3 = 0$ Equation 2

From two given equations, we can find the value of both x and y by finding the value of one variable from any one of the two equations in terms of other variable and putting it to other equation.

Solving equation 1

Finding 'y' in terms of 'x' $2x+y=12\\y=12-2x$ Equation 3

Putting above equation in equation 3 in 2

$x + y + 3 = 0$

$x+12-2x+3=0$

$x=15$

Putting value of 'x' in equation 3 to find the value of 'y'

$y=12-2(15)\\y=12-30\\y= -18$
