Here’s the correct answer and how I got it :)
Answer:
-14
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x/2-5=-12
1/2x+-5=-12
1/2x-5=-12
Step 2: Add 5 to both sides.
1/2x-5+5=-12+5
1/2x=-7
Step 3: Multiply both sides by 2.
2*(1/2x)=(2)*(-7)
x=-14
Here is the answer. I tried to send it vertically but I will send it horizontally again this time. Let me know if it is uncomfortable to see. Feel free to ask me!
Solution: Find the relationship among the 3 sides and solve for the unknown.
First side = x
second side = x + 3
third side = 3x - 10
x + x + 3 + 3x - 10 = 23
5x - 7 = 23
5x = 30
x = 6 <========== shortest side
