Solve Systems Of Linear Equations With Substitution Khan Academy Wiki To solve a system of equations using substitution 1. isolate one of the variables in one of the equations, e.g. rewrite 2x y=3 as y=3 2x. 2. you can now express the isolated variable using the other one. *substitute* that expression into the second equation, e.g. rewrite x 2y=5 as x 2 (3 2x)=5. 3. now you have an equation with one variable!. Write a system of linear equations that represents this situation where x represents the amount invested in the 3.5% fund and y represents the amount invested in the 5.5% fund. solve this system of to determine the smallest amout that you can invest at 5.5% in order to meet your objective.
