Answer 2

Solving the System of Equations

To solve the system of equations 4x - 6y = 26 and 5x - 3y = 1, we can use the method of addition. The goal is to eliminate one variable by adding the two equations together. Here's how we can do it:

1. Multiply the first equation by 5 and the second equation by 4 to make the coefficients of x in both equations the same: - Equation 1: 20x - 30y = 130 - Equation 2: 20x - 12y = 4

2. Subtract Equation 2 from Equation 1 to eliminate x: - (Equation 1) - (Equation 2): -18y = 126

3. Solve for y by dividing both sides of the equation by -18: - y = -7

4. Substitute the value of y back into one of the original equations to solve for x. Let's use the first equation: - 4x - 6(-7) = 26 - 4x + 42 = 26 - 4x = -16 - x = -4

Therefore, the solution to the system of equations is x = -4 and y = -7.
