Solving Linear Systems by Elimination Answers

Use the drop-down menus to solve the system using the 5-step process you just learned.x + 6y = 292x - 4y = -61) Solve for x in the first equation: x =

2) Substitute the expression you got into the other equation:2() – 4

3) Simplify and solve for the variable that remains: y =

4) Back substitute y = 4 and solve: x =

(,

).

5) Check your solution.x + 6y = 29

2x - 4y = -6

Fill in the boxes below with the numbers 1-5.The Substitution Method Back substitute and solve for the first variable. Substitute the expression you got into the other equation. Simplify and solve for the variable that remains. Solve for either x or y in one of the equations. Check your solution.

Do not solve the system below. Its solution is (x, y) = (1, 1). Instead, answer the questions.3x + 4y = 75x + 10y = 15If you were going to solve the system above, what would be the best first step according to the strategy you just learned?
