2. Standard Form of a Quadratic Function
Sign In
Example Solution: Substitution Method, because one variable has a coefficient of 1.
Solution: (3,2)
In this system of equations, at least one of the variables has a coefficient of 1. Therefore, we will approach its solution with the Substitution Method. When solving a system of equations using substitution, there are three steps.
(I):n= 5m-13
(I):Distribute 3
(I):Add terms
(I): LHS+39=RHS+39
(I):.LHS /17.=.RHS /17.
(II):m= 3
(II): Multiply
(II):Subtract term
