Answer:
73 - Explanation and Check below
Step-by-step explanation:
11x - 4 = 9x + 10
1. Get variable (x) on one side.
11x - 4 = 9x + 10
- 9x - 9x
2x - 4 = 10
2. Solve 2 step equation - add 4 on both sides of equation.
2x - 4 = 10
+ 4 + 4
3. Divide 2 on both sides of equation.
2x = 14

2 2
x = 7
Check:
11 (7) - 4 = 9(7) + 10
77 - 4 = 63 + 10
73 = 73 True statement.
Step-by-step explanation:
If a transversal intersects two parallel lines, the corresponding angles will be always equal.
So in the problem, the two given equations are equal to each other.
The answer for the two angles with equations is 73.
Also, the angles vertical to the two equations are also 73 because vertical angles are congruent (equal).
Hope this helps :)
