Explain how to apply substitution in solving a system of equations. 3)If the signs are different then add the two equation’s so that like terms get eliminated. 4)The value of one variable is calculated 5)By substituting the value of known variable unknown variable can be found. a. Demonstrate each technique in solving the system 3x + 9y = 12 5x - 4y = 3 Solution: 1. 3x + 9y = 12 2. 5x - 4y = 3 1)L.C.M of 3,5 = 15 hence bring the co-efficient of x to 15 multiply equations(1) by 5 , and equations(2) by 3. The two equations reduces to 15x+45y = 60 15x-12y = 9 2) subtract the two equations we get 57y = 51 , y = 51/57 3) substituting the value of y in equations (1) we get 3x+9(51/57) = 12 3x = 12- (459/57) = 684-459/57 = 225/57 x = 225/57*3 = 75/57 solution is x = 75/57 and y = 51/57 Thank you for your help.
