WebHow to graph Inequalities 1 - Algebra Help - ExplainingMaths.com IGCSE GCSE Maths Watch on The bset way to learn and understand maths is by solving example questions yourself. Check the following maths video … WebIf we have one equation and one unknown/variable, we can solve the equation (eg 2x + 1 = 9). When we have two unknowns/variables we need two equations to find both their values. In that case we are solving two equations simultaneously (at the same time). In the past we have learned two strategies to do so successfully; the substitution and the ...
