EXPLANATION
By the Parallel lines cuted by a transversal line Theorem, we can see that 5x and 2x+ 5 perform a linear pair because both lines are parallel so they are supplementary angles as shown as follows:
2x + 5 + 5x = 180
Adding like terms:
7x + 5 = 180
Subtracting -5 to both sides:
7x = 180 - 5
Subtracting numbers:
7x = 175
Dividing both sides by 7:
x = 175/7
Simplifying:
x=25
Answers:
Equation --->
(2x+5) + 5x = 180
x = 25
