Answer 2

To solve the system of equations:

1. Y = x - 5
2. 4x + y = 10

We can use the method of substitution or elimination. Let's solve it using substitution.

Step 1: Solve the first equation for y in terms of x. Y = x - 5

Step 2: Substitute the expression for y in the second equation. 4x + (x - 5) = 10

Step 3: Simplify and solve for x. 5x - 5 = 10 5x = 15 x = 3

Step 4: Substitute the value of x back into the first equation to find y. Y = 3 - 5 Y = -2

Therefore, the solution to the system of equations is x = 3 and y = -2.
