6-2A Solving by Substitution Warm-up (IN) Learning Objective: to solve systems of equations using substitution Graph and solve the system of equations.

2
Notes Learning Objective: to solve systems of equations using substitution Was it easy to find the intersection point? Graphing is the least accurate way to solve! ***To solve systems by substitution: 1 – get one variable by itself in one equation 2 – Substitute that expression into the other equation 3 – Solve for the variable 4 – plug that value back into either of the original equations to find the other variable

Learning Objective: to solve systems of equations using substitution EX 1 – Solve by substitution: 1 – get one variable by itself in one equation 2 – Substitute that expression into the other equation 3 – Solve for the variable 4 – plug that value back into either of the original equations to find the other variable Always write solution as an ordered pair!!!
