Linear Equation - Solve for Box, Three Terms, Add and Subtract (Level 1)

This math topic covers solving linear equations where a symbol (a circle here) represents the unknown variable. The primary skills practiced involve simple arithmetic operations—addition and subtraction with three terms. Students are exposed to finding the value of the symbol that makes the linear equation correct. Each problem consists of an equation where students have to derive the value of the circle through manipulation and calculation, balancing both sides of the equation. This topic falls under introductory concepts of algebra.
