Solving systems of equations using substitution
This week in Pre Calc 11, I learned how to solve systems of equations using substitution. A method of how to solve a linear system is to use the substitution method. You use the substitution method by substituting one y-value in an equation with the other. While using the substitution method, you first substitute y in the second equation with the first equation since y = y. After substituting y into the equation and solving for x, the value of x can then be used to find y by substituting the number you found, with x. While using the substitution method you can also start by substituting x in the second equation with the first equation.
