Question

look at the diagram.
which equation can be used to solve for x?
13x + 90 = 180 9x = 180 9x + 90 = 180 5x + 90 = 180
solve for x.
x = i

Explanation:

Step1: Solve the equation

We have the equation \(9x + 90=180\).
Subtract 90 from both sides:
\(9x+90 - 90=180 - 90\)
\(9x = 90\)

Step2: Find the value of \(x\)

Divide both sides by 9:
\(x=\frac{90}{9}\)

Answer:

\(x = 10\)
