Solve x/2+3 = 9

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

Equation

Answer

x = 12

x/2+3=9

Solve the equation by isolating x:

Step 1 — Clear fractions

Multiply every term by 2 to clear fractions:

2 · x/2 = x

2 · 3 = 6

2 · 9 = 18

The equation becomes:

x + 6 = 18

Step 2 — Subtract 6 from both sides

Move the constant 6 to the right side:

x + 6 − 6 = 18 − 6

x = 12

How to solve x/2+3 = 9

To solve x/2+3 = 9, isolate x by performing inverse operations on both sides — first removing constants, then dividing by the coefficient of x. This gives x = 12.
