This is a self practice activity to help students master equivalent linear equations.
Updated on 15 Oct 23.
Fixed small error which marked answer as wrong if the solution involves the coefficient of x being 1 on the left side and the user puts the term in x after the term in y.
Also enhanced the applet by fixing vertical alignment of the labels of the buttons for arithmetic operations.
Added general feedback about balancing operations on the equation when any of the answers are wrong
