Answer 2

It seems like you've provided a system of two linear equations with two variables, x and y. Let's solve this system step by step.

The given system of equations is:

1. 0.75x + 1/8y + 1 = 1.37x - 0.65y
2. 0.65y + 0.01x = 0

Let's simplify the equations and solve for one variable in terms of the other:

From equation 2, we can solve for y: 0.65y + 0.01x = 0 0.65y = -0.01x y = -0.01x / 0.65

Now we can substitute this expression for y into equation 1:

0.75x + 1/8 * (-0.01x / 0.65) + 1 = 1.37x - 0.65 * (-0.01x / 0.65)

Simplify the equation:

0.75x - 0.001923x + 1 = 1.37x + 0.01x

Combine the x terms:

0.758077x + 1 = 1.38x

Now, subtract 0.758077x from both sides:

1 = 1.38x - 0.758077x 1 = 0.621923x

Now, solve for x:

x = 1 / 0.621923 x ≈ 1.608

Now that we have the value of x, we can substitute it back into the equation we found for y:

y = -0.01x / 0.65 y = -0.01 * 1.608 / 0.65 y ≈ -0.0246

So, the solution to the given system of equations is approximately: x ≈ 1.608 y ≈ -0.0246
