Let’s go over some essential algebra terms: Variable. The letter hiding the solution, commonly “x.” Constant. Known numbers in the equation. In the equation 2+3=x, 2 and 3 are the constants.

For example, in the expression \(3(m + 7)\), multiply both \(m\) and 7 by 3, so: \(3(m + 7) = 3 \times m + 3 \times 7 = 3m + 21\). Expanding brackets involves using the skills of simplifying algebra.
