Introduction
In the earlier classes, you have come across several algebraic expressions and equations.
ne examples of expressions we have so far worked with are:
5x, 2x - 3, 3x + y, 2xy + 5, xyz + x + y + z, x? + 1, y + y2
5.
ne examples of equations are: 5x = 25, 2x – 3 =9, 2y +
37
6z + 10 = -2
2.

a would remember that equations use the equality (=) sign; it is missing in expressions.
Of these given expressions, many have more than one variable. For example, 2xy +5
two variables. We however, restrict to expressions with only one variable when we
mequations. Moreover, the expressions we use to form equations are linear. This means
the highest power of the variable appearing in the expression is 1.
ese are linear expressions:
5
2x, 2x + 1, 3y - 7, 12 - 5z, + (x - 4)+10
