PLEASE ANSWER STEP BY STEP....I'll MARK U AS BRAINLIEST...​

Answer 1

Simplifying

7p + -3q + 2p + 5q = 0

Reorder the terms:

7p + 2p + -3q + 5q = 0

Combine like terms: 7p + 2p = 9p

9p + -3q + 5q = 0

Combine like terms: -3q + 5q = 2q

9p + 2q = 0

Solving

9p + 2q = 0

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-2q' to each side of the equation.

9p + 2q + -2q = 0 + -2q

Combine like terms: 2q + -2q = 0

9p + 0 = 0 + -2q

9p = 0 + -2q

Remove the zero:

9p = -2q

Divide each side by '9'.

p = -0.2222222222q

Simplifying

p = -0.2222222222q
