FAQ

How do I solve a linear equation?

Isolate x by performing inverse operations: subtract/add to move constants, then divide by x's coefficient.

What if there's no solution?

Some equations like x + 1 = x + 2 have no solution (contradiction). Our calculator identifies these cases.

What if there are infinite solutions?

Equations like 2x + 4 = 2(x + 2) are always true (identity), giving infinite solutions.

Can this solve for other variables?

Yes, rearrange your equation so the target variable is in the x position.
