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

Equation
Answer
x = 5

3x+7=22

Solve the equation by isolating x:

Step 1 — Subtract 7 from both sides

Move the constant 7 to the right side:

3x + 7 − 7 = 22 − 7

3x = 15

Step 2 — 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+7 = 22

To solve 3x+7 = 22, isolate x by performing inverse operations on both sides — first removing constants, then dividing by the coefficient of x. This gives x = 5.
