Answer:
x = -1
Step-by-step explanation:
To solve this type of mathematical problem, you need to set up an equation.
Since AB = 5 and BC = 2x + 6, AC must = 2x + 6 + 5.
AC is also given another equivalent value, x + 10. That means an equation is given to solve for x:
2x + 6 + 5 = x + 10
Time for solving!
2x + 6 + 5 = x + 10 First, bring x to one side by subtracting x on both sides.
x + 6 + 5 = 10 Now, simplify the equation to make it more readable.
x + 11 = 10 Lastly, isolate x by subtracting 11 from both sides.
x = -1
The value of x is -1
