Whats the answer to this question

An exterior angle is equal to the sum of the two opposite inside angles.
45x = 25x + 57 +x
Simplify the right side:
45x = 26x +57
Subtract 26x from each side:
19x = 57
Divide each side by 19"
x = 57 / 19
x = 3
Answer:
x = 3
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠QRT is an exterior angle and ∠'s RTS and RST are the opposite interior angles, hence
45x = 25x + 57 + x
45x = 26x + 57 ( subtract 26x from both sides )
19x = 57 ( divide both sides by 19 )
x = 3
