Answer 2

It looks like you have an equation with two variables, x and y. Let's solve it step-by-step.

The equation provided is:

2x - 1 - (9 - 5y) = 0

Now, we have another set of equations:

1. 6x + 8 = 0
2. 2x = 1.5y + 2.5

Let's proceed with solving the equation and the system of equations.

Step 1: Solve the equation 2x - 1 - (9 - 5y) = 0

To simplify the equation, let's remove the parentheses:

2x - 1 - 9 + 5y = 0

Combine the constants:

2x + 5y - 10 = 0

Step 2: Solve the system of equations:

1. 6x + 8 = 0

Subtract 8 from both sides:

6x = -8

Now divide both sides by 6 to solve for x:

x = -8/6 x = -4/3

2. 2x = 1.5y + 2.5

Substitute the value of x into this equation:

2 * (-4/3) = 1.5y + 2.5

Multiply both sides by 3 to eliminate the fraction:

-8 = 4.5y + 7.5

Now, let's isolate y on one side of the equation:

4.5y = -8 - 7.5 4.5y = -15.5

Finally, divide both sides by 4.5 to find the value of y:

y = -15.5 / 4.5 y ≈ -3.44 (rounded to two decimal places)

So, the solution to the system of equations is approximately x = -4/3 and y ≈ -3.44.
