Here we'll review solving various types of linear equations. A linear equation is one that has a variable of degree 1 Here are the skills you need to do well in this unit. Trial & Error    Guessing the answer BASIC 1    Equations in the form   ax = b BASIC 2    Equations in the form   ax + b = c SIMPLIFY FIRST    Equations in the form   ax + bx + c = d SIMPLIFY FIRST    Equations in the form   a(bx + c) = d VARIABLE ON RIGHT    Equations in the form   ax = bx + c COMBINATION 1    Equations in the form   ax + b = cx + d COMBINATION 2    Equations in the form   a(bx + c) = dx + e FRACTIONS 1    Equations in the form    FRACTIONS 2    Equations in the form    FRACTIONS 3    Equations in the form    Checking ... Why checking has to be done in the original equation In all the formats illustrated above, a, b, c, d and e are understood to be integers (positive or negative whole numbers). Note for Teachers We use the balanced equations method for solving equations, as equation solving is a new topic for students. The transposition method should not be used at this level, as it does not promote understanding of how equality and equations work. Resources HTML, animations & design by Bill Willis 2025
