A) 2x + y - 12 = 0 x + y + 3 = 0

AVprozaik [17]

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'

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

Okay, so in order to find how much she earns per hour you'll take the salary she earns each week ($198.60) and divide that to how many hours she works every week (15 hours). It'll look like: 198.60 / 15= $13.24 per hour.
