Answer 1

Answer:

q = 13 because if we add 9 to 4 it will be 13

Answer 2

Answer:

Simplifying

9 = q + -4

Reorder the terms:

9 = -4 + q

Solving

9 = -4 + q

Solving for variable 'q'.

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

Add '-1q' to each side of the equation.

9 + -1q = -4 + q + -1q

Combine like terms:

q + -1q = 0 9 + -1q = -4 + 0

9 + -1q = -4

Add '-9' to each side of the equation.

9 + -9 + -1q = -4 + -9

Combine like terms: 9 + -9 = 0

0 + -1q = -4 + -9

-1q = -4 + -9

Combine like terms: -4 + -9 = -13

-1q = -13

Divide each side by

'-1'. q = 13

Simplifying q = 13
