<span>Simplifying
10 + -3(3x + -40) = -9x
Reorder the terms:
10 + -3(-40 + 3x) = -9x
10 + (-40 * -3 + 3x * -3) = -9x
10 + (120 + -9x) = -9x
Combine like terms: 10 + 120 = 130
130 + -9x = -9x
Add '9x' to each side of the equation.
130 + -9x + 9x = -9x + 9x
Combine like terms: -9x + 9x = 0
130 + 0 = -9x + 9x
130 = -9x + 9x
Combine like terms: -9x + 9x = 0
130 = 0
Solving
130 = 0
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.</span>

Answer:
(a) The net profit for walking 3 dogs is $40
(b) The net profit for walking 6 dogs is $100
Step-by-step explanation:
There are mistakes in your question; however, the correct given parameter is

Required
Interpret p(3) = 40 & p(6) = 100
Interpreting p(3) = 40
Comparing this to 
d = 3 & p(d) = 40
This implies that:
The net profit for walking 3 dogs is $40
Interpreting p(6) = 100
Comparing this to 
d = 6 & p(d) = 100
This implies that:
The net profit for walking 6 dogs is $100
