Solving Linear Systems by Substitution 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 = 6y - 29x - 29✔ -6y + 29

2) Substitute the expression you got into the other equation:2(X y–6x + 29✔ –6y + 29) – 4

Therefore, the solution is (x, y) =

3) Simplify and solve for the variable that remains: y = ⇒ 4

4) Back substitute y = 4 and solve: x = ⇒ 5

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?
