Aim #23: How do we solve a system of equationsalgebraically using the substitution method? Homework: Handout Do Now: Consider the two system of equations below. Verify whether the given ordered pairs are solutions: (3,4) (2, 2.4) y = x + 1 4x + 5y = 20
Besides solving a system of equations GRAPHICALLY , another method is the SUBSTITUTION METHOD. By replacing one variable with an equivalent expression containing the other variable, you can create a one-variable equation to solve. Example 1: y = 2x + 1 x - y = 7 Check your solution! Example 2: 2x + y = 4 2x + 3y = 9 Check your solution!
HW #22 Solutions: (p.^189 #s^ 14-21).
Sum it Up! To determine the solution to a system of equations, we have found the solutions ____________ and ____________ using ____________. How can you verify the solution to a system of equations? e) y = 0.2x + 10 f) 4x + 3y = 27 4x + 5y = 35 y = 2x - 1 g) Is (-2,-7) the solution of the following system? Explain. 7y - 4x = 29 x = y -
