Multiply the bracket by 5

I used PEMDAS

P= parenthesis

E= exponents

M=multiplication

D= division

A= addition

S= subtraction

7r+2= 5(r-4)

7r+2= 5r-20

Move 5r to the left hand side . Positive 5r changes to negative 5r

7r-5r+2= 5r-5r-20

2r+2=- 20

2r+2-2= -20-2

Move positive 2 to the right hand side. Changes to negative -2

2r+2-2= -20-2

2r= -22

Divide by 2 for 2r and -22

2r/2= -22/2

r= -11

Answer is r= -11

Answer:

r = (-11)

Step-by-step explanation:

7r + 2 = 5(r – 4) ​

7r + 2 = 5r – 4 * 5

7r + 2 = 5r – 20

7r - 5r = -20 - 2

     2r = -22

       r = -22/2 = (-11)

6m + 2 - 4m =<br><br><br>help with this please ​
devlian [24]

The answer is: 2(m+1)


First combine like terms.
<em>we do 6m-4m which is 2m</em>
2m+2=?

Second we factor. We notice that both terms have 2.
2(m+1)

<em>by distributive law, the 2 is distributed to m and 1.
</em>
