Answer:

4=0

Explanation:

Simplifying

(-9p + 7) + -1(-9p + 3) = 0

Reorder the terms:

(7 + -9p) + -1(-9p + 3) = 0

Remove parenthesis around (7 + -9p)

7 + -9p + -1(-9p + 3) = 0

Reorder the terms:

7 + -9p + -1(3 + -9p) = 0

7 + -9p + (3 * -1 + -9p * -1) = 0

7 + -9p + (-3 + 9p) = 0

Reorder the terms:

7 + -3 + -9p + 9p = 0

Combine like terms: 7 + -3 = 4

4 + -9p + 9p = 0

Combine like terms: -9p + 9p = 0

4 + 0 = 0

4 = 0

Solving

4 = 0
