9-c=-13:
solve it, show your ! i need this done extra points !

c is equal to twenty-two ^_^

c = 22

Step-by-step explanation:

9 - c = -13

To solve this, we must get c alone on one side.

So, subtract 9 from both sides.

9 - c = -13

-c = -22

Subtracting 9 from both sides gives us -c = -22. However, we want a positive c, not negative c.

So normally, divide both sides by negative 1.

[In this case, since both sides have a negative sign, the cancel each other out, so you can just get rid of both negative signs.]

-c = -22

c = 22

So, c = 22

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
