6(r-4)-5(r-1)=2(r+6) r=?

r = -31

Step-by-step explanation:

The picture is how I solved it.

r=-31

Step-by-step explanation:

To find r, we want to use algebraic properties to isolate r.

6(r-4)-5(r-1)=2(r+6)             [distribute]

6r-24-5r+5=2r+12             [combine like terms]

r-19=2r+12                          [subtract both sides by 2r]

-r-19=12                               [add both sides by 19]

-r=31                                    [divide both sides by -1]

r=-31

Now, we know that r=-31.

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
