Question

Solve for p in the literal equation 4p + 3r =9.
p=

Answer 1

p= -3/4r+9

Explanation:

1. Subtract 3r from both sides of the equation to isolate p on one side of the equation

a. 4p+3r - 3r= 9 -3r

b. 4p=9-3r

2. Divide every term in the equation by 4

a. 4p/4=9/4 - 3r/4

b. p=9/4 -3r/4

3. Rearrange the equation (if need be) into slope-intercept form.

a. p= -3r/4 +9/4

Answer 2

p= 9/4 - 3r/4

Explanation:

Move 3r to the right and when you divide 4 from both sides and each variable, you are left with p= 9/4 - 3r/4 since you cannot simplify it more.
