If 3x=9x-15 then x + 5=?
1 Answer | add yours
We need to determine the value of x to find out what is the result of the sum x + 5.
For this reason, we'll solve the given equation.
We'll isolate the terms in x to the left side:
3x - 9x = -15
-6x = -15
We'll divide by -6 both sides:
x = -15/-6
x = 5/2
Now, we'll perform the addition:
x + 5 = 5/2 + 5
x + 5 = (5 + 2*5)/2
x + 5 = 15/2
The result of the sum x + 5 is 15/2.
