Can someone help me with this asap

x = 55

Step-by-step explanation:

1. We can use exterior angle theorem to find the value of x. The exterior angle theorem states that the exterior angle of a triangle is equal to the sum of the two remote angles in that same triangle.

2. (Solving)

Step 1: Simplify both sides of the equation.

Step 2: Subtract 2x from both sides.

Step 3: Subtract 39 from both sides.

Step 4: Divide both sides by -1.

Step 4: Check if solution is correct.

Therefore, x = 55.

so, converting firstly the mixed fractions to improper fractions and then "adding".
