Step-by-step explanation:
For those 2 lines to parallel to each other, then the 2 angles have to be alternate interior and have to be congruent. The value of x that makes them congruent is found by setting the 2 expressions equal to each other and solving for x:
x = 4.5
Answer:
4.5
Step-by-step explanation:
The two angles are equal
This means that: 6x + 42 = 18x - 12
Rearrange the equation to get x on one side and the integers on the other.
42 + 12 = 18x - 6x
54 = 12x
54/12 = x
x = 9/2 = 4.5
