Solve x-9 = 0

Solve linear, quadratic, cubic, radical, exponential, and logarithmic equations step by step.

Equation
Answer
x = 9

x-9=0

Solve the equation by isolating x:

Step 1 — Add 9 to both sides

Move the constant −9 to the right side:

x − 9 + 9 = 0 + 9

x = 9

x = 9

-2 2 4 6 8 10 -12.5 -10 -7.5 -5 -2.5 2.5 (9, 0) (0, -9)

How to solve x-9 = 0

To solve x-9 = 0, isolate x by performing inverse operations on both sides — first removing constants, then dividing by the coefficient of x. This gives x = 9.
