solve simple equations and inequalities by the method of drawing graphs
make logically precise statements in some simple and familiar situations
1.1 EQUATIONS AND THEIR SOLUTIONS
ax + b = 0 (1.1)
is probably the simplest of all mathematical equations. We assume that the constants a and b are known and try to find the value of x, which would satisfy equation (1.1).
Quantities whose values have to be found out from the given equations are called unknowns. Equation (1.1) is an example of a linear ...
