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

Equation

Answer

x = 3

5x-3=12

Solve the equation by isolating x:

Step 1 — Add 3 to both sides

Move the constant −3 to the right side:

5x − 3 + 3 = 12 + 3

5x = 15

Step 2 — Divide both sides by 5

Isolate x by dividing both sides by the coefficient 5:

5x / 5 = 15 / 5

x = 3

How to solve 5x-3 = 12

To solve 5x-3 = 12, isolate x by performing inverse operations on both sides — first removing constants, then dividing by the coefficient of x. This gives x = 3.
