Simultaneous Equations

QuestionAnswer
What are simultaneous equations? When two equations are both satifyed for the same values for x and y.
Elimination Method In this method, we 'eliminate' one of the variables .
Unable to be eliminated by adding or subtracting Multiply one or both of the equations by a number to make elimination possible.
Equations containing fractions. To solve these equations, we get rid of the fractions by multiplying each term.
Solving Simultaneous equations graphically. Two simultaneous equations may be solved by drawing graphs of the two equations and then reading the x-value and the y-value of their point of intersection.
Using simultaneous equations to solve problems Simultaneous equations are particularly useful for solving problems which have two unknowns. Generally, two different pieces of information enable us to write down two equations.
