Answer 2

To solve this system of equations, you can follow these steps:

1. Simplify each equation as much as possible.
2. Solve for the variable x in each equation.

Let's start with the first equation:

(450 - 300) - x = 450

Simplify the left side:

150 - x = 450

Now, subtract 150 from both sides of the equation to isolate x:

• x = 450 - 150
• x = 300

Now, let's move on to the second equation:

450x - (315 - 245) = 526

First, simplify the expression inside the parentheses:

450x - (70) = 526

Now, add 70 to both sides of the equation to isolate 450x:

450x = 526 + 70 450x = 596

Next, divide both sides by 450 to solve for x:

x = 596 / 450 x = 1.324

Finally, let's solve the third equation:

(859 - 259) / x = 200

First, simplify the numerator on the left side:

(600) / x = 200

Now, multiply both sides of the equation by x to isolate x in the denominator:

600 = 200x

Divide both sides by 200 to solve for x:

x = 600 / 200 x = 3

So, the solution to the system of equations is x = 300, x = 1.324, and x = 3. These values do not form a consistent solution, which suggests there may be an error in one of the original equations. Please double-check the equations to ensure accuracy.
