Answer 1

Step-by-step explanation:

Given evaluate 7 – 5p + 3q when p = 1 and q = 7

• We need to find the value of the given equation by substituting the given values.
• Now substituting the value of p and q in the given equation we get
• So given p = 1 and q = 7
• So equation is 7 – 5p + 3q
•                   = 7 – 5(1) + 3(7)
•                  = 7 – 5 + 21
•                  = 28 – 5
