How do you solve #9x - 15 = 0#?

Answer 1

Genesis Allen

#x = 5/3#

Step 1) Isolate the #x# term on one side of the equation while keeping the equation balanced:

#9x - 15 + 15 = 0 + 15#

#9x - 0 = 15#

#9x = 15#

Step 2) Solve for #x# while keeping the equation balanced"

#(9x)/9 = 15/9#

#(cancel(9)x)/cancel(9) = (3*5)/(3*3)#

#x = (cancel(3)*5)/(cancel(3)*3)#

#x = 5/3#

To solve the equation (9x - 15 = 0):

Add 15 to both sides of the equation to isolate the term with (x) on one side: [9x = 15]
Divide both sides of the equation by 9 to solve for (x): [x = \frac{15}{9}]
Simplify the fraction on the right side if possible: [x = \frac{5}{3}]

Therefore, the solution is (x = \frac{5}{3}).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
