Equation
Answer
x = 5

3x=15

Solve the equation by isolating x:

Step 1 — Divide both sides by 3

Isolate x by dividing both sides by the coefficient 3:

3x / 3 = 15 / 3

x = 5

x = 5

-1 1 2 3 4 5 6 -20 -15 -10 -5 5 (5, 0) (0, -15)

How to solve 3x = 15

To solve 3x = 15, isolate x by performing inverse operations on both sides — first removing constants, then dividing by the coefficient of x. This gives x = 5.
