Question

9x + 50 = 20 - x

Explanation:

Step1: Move x terms to left and constants to right

Add \( x \) to both sides and subtract 50 from both sides:
\( 9x + x = 20 - 50 \)

Step2: Combine like terms

Simplify both sides:
\( 10x = -30 \)

Step3: Solve for x

Divide both sides by 10:
\( x = \frac{-30}{10} = -3 \)

Answer:

\( x = -3 \)
