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:
y = -1/3x -2
Step-by-step explanation:
Slope intercept form of a line is
y= mx+b
We need to solve for y
1/3x +y = -2
Subtract 1/3x from each side
1/3x -1/3x +y =-1/3x -2
y = -1/3x -2
