We know that the sum of the measures of two supplementary angles is 180 degrees. So, we can write the equation as:
(2x - 25) + 110 = 180
Simplifying the equation, we get:
2x - 25 + 110 = 180
2x + 85 = 180
Subtracting 85 from both sides, we have:
2x = 95
Dividing both sides by 2, we get:
x = 47.5
Therefore, the equation to solve for x is: 2x + 110 = 180.
