Pan Balance: Solve Linear Equations

Aim: Solve linear equations in one variable by performing the same operation on both sides of a virtual pan balance — just like keeping a real weighing scale level. Isolate x to find its value.

Problem 1 / 5Solved: 0

Current Equation

2x + 3 = 11

Apply an operation to BOTH sides:
