e=3.
So this is how I approached this. Since 7 is being multiplied, I divided both sides by 7 so 105/7 = 15. Then it becomes simple as 5e=15. We divide both sides by 5 and get e=3. Tip: just try isolating the variable and then life is much easier.
Answer:
C. Construction X because point C is the incenter of triangle LMN.
Step-by-step explanation:
The construction requires that the school must be at equal distance to cities of the triangle town. Thus, it must be located at the point of intersection of the straight path from the three cities L, M, and N.
To be able to construct the school with the specification, option C is the most suitable. Construction X describe the appropriate method because point C is the incenter of triangle town of cities L, M, and N.

➷ Form an equation with 'x' as the unknown number
7x + 3 = -74
Subtract 3 from both sides:
7x = -77
Divide both sides by 7:
x = -11
The number is -11
