Answer: 0

Step-by-step explanation:

Simplifying

9x2 + 49x = 22 + -5x

Reorder the terms:

49x + 9x2 = 22 + -5x

Solving

49x + 9x2 = 22 + -5x

Solving for variable 'x'.

Reorder the terms:

-22 + 49x + 5x + 9x2 = 22 + -5x + -22 + 5x

Combine like terms: 49x + 5x = 54x

-22 + 54x + 9x2 = 22 + -5x + -22 + 5x

Reorder the terms:

-22 + 54x + 9x2 = 22 + -22 + -5x + 5x

Combine like terms: 22 + -22 = 0

-22 + 54x + 9x2 = 0 + -5x + 5x

-22 + 54x + 9x2 = -5x + 5x

Combine like terms: -5x + 5x = 0

-22 + 54x + 9x2 = 0
