Let "x" be the cost of each bat. Let "y" be the cost of each ball. Then, 7x + 6y = 3800 ----- (1) 3x + 5y = 1750 ----- (2) Solve (1) for y. 6y = 3800 - 7x. y = (3800 - 7x)/6 ----- (3) Substitute y = (3800 - 7 x)/6 in (2)

Substitution Method (Systems of Linear Equations) When two equations of a line intersect at a single point, we say that it has a unique solution which can be described as a point, \color{red}\left( {x,y} \right), in the XY-plane. The substitution method is used to solve systems of linear equation by finding the exact values of x and y which correspond to the point of …

The substitution method for solving recurrences is famously described using two steps: Guess the form of the solution. Use induction to show that the guess is valid. This method is especially powerful when we encounter recurrences that are non-trivial and unreadable via the master theorem. We can use the substitution method to establish both upper and lower bounds on …

y = 11/5. Step 5: Now, substitute the value of y in any of the given equations. Let us substitute the value of y in equation (2). x + 4y + 2 = 0. x + 4 × (11/5) + 2 = 0. x + 44/5 + 2 = 0. x + 54/5 = 0. x = -54/5. Therefore, after solving the given linear equations by substitution method, we get x = -54/5 and y= 11/5.

Substitution Method. One of the methods to solve a system of linear equations in two variables algebraically is the substitution method. In this method, we find the value of any one of the variables by isolating it on one side and taking every other term on the other side of the equation.

If you substitute the values x = − 3 and y = 2 into the first equation, you get a false statement: 2 (2) = − 3 + 9. To solve this system, try rewriting the first equation as x = 2 y − 8. Then substitute 2 y − 8 in for x in the second equation, and solve for y. The correct answer is x = − 2, y = 3. B) x = − 2, y = 3.
