Solve 2(x+5) = 18

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

Equation

Answer

x = 4

2(x+5)=18

Solve the equation by isolating x:

Distribute:

2(x+5) = 2x + 10

The equation becomes:

2x + 10 = 18

Step 1 — Subtract 10 from both sides

Move the constant 10 to the right side:

2x + 10 − 10 = 18 − 10

2x = 8

Step 2 — Divide both sides by 2

Isolate x by dividing both sides by the coefficient 2:

2x / 2 = 8 / 2

x = 4

How to solve 2(x+5) = 18

To solve 2(x+5) = 18, isolate x by performing inverse operations on both sides — first removing constants, then dividing by the coefficient of x. This gives x = 4.
