Question

m∠udr=63°
two labeled angles are adjacent angles.
means that their measures sum to 63°.
the relationship you determined to write an equation to help you solve for x.
9x + 5x = 63
for x. write your answer as an integer or decimal.
solution history
9x + 5x = 63
hint
the coefficient is 14. what value can you multiply both sides of the equation by so that the coefficient becomes 1?

hint 2 of 3

Explanation:

Step1: Combine like terms

The equation is \(9x + 5x = 63\). Combining the terms with \(x\), we get \(14x = 63\) since \(9x + 5x=(9 + 5)x = 14x\).

Step2: Solve for \(x\)

To solve for \(x\), we divide both sides of the equation \(14x = 63\) by 14. So \(x=\frac{63}{14}\). Simplifying this fraction, we get \(x = 4.5\).

Answer:

\(4.5\)
