Question

look at the diagram.
which equation can be used to solve for x?
solve for x.
x =

Explanation:

Step1: Use the linear - pair property

Angles on a straight line sum to \(180^{\circ}\). Here, \((9x)^{\circ}\) and \(126^{\circ}\) form a linear pair. So, the equation is \(9x + 126=180\).

Step2: Solve the equation for \(x\)

Subtract \(126\) from both sides of the equation \(9x + 126 = 180\):

$$
LATEXBLOCK0
$$

Divide both sides by \(9\):

$$x=\frac{54}{9}=6$$

Answer:

The equation is \(9x + 126 = 180\) and \(x = 6\)
