HELP THIS IS DUE IN 15 MINUTES I DONT KNOW HOW TO SOLVE IT!!!

(x,y)=(-10, -30)

Step-by-step explanation:

x/4 -y/12 = 0

--> x/4 = y/12

substitute into the first eq.

x/4 + y/12 = -5

y/12 + y/12 = -5

2y/12 = -5

y= (-5) * 12/2 = -30

solve for x, x/4 = (-30)/12

x=4* (-30)/12 = -10

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
