Answer 2

It seems like you've provided a series of equations with variable x. Let's break down and solve each equation step by step:

1. (90:9) * x = 50x + 27

   First, simplify the left side of the equation: 10 * x = 50x + 27

   Now, subtract 50x from both sides: 10x - 50x = 27

   Combine like terms: -40x = 27

   Divide both sides by -40 to solve for x: x = 27 / -40 x = -27/40

2. 5 * 12 * (x - 200) + 300

   Start by simplifying the expression inside the parentheses: 5 * 12 * (x - 200) + 300 = 60 * (x - 200) + 300

   Now, distribute the 60 to both terms inside the parentheses: 60x - 60 * 200 + 300

   Simplify further: 60x - 12000 + 300

   Combine like terms: 60x - 11700

3. 450 * (x * 60) - 48

   First, calculate the product inside the parentheses: 450 * (x * 60) - 48 = 450 * 60x - 48

   Now, calculate 450 * 60: 27000x - 48

4. 194

Now, equate the expressions from steps 1, 2, and 3 to 194 and solve for x:

-27/40 + (60x - 11700) + (27000x - 48) = 194

Combine like terms: -27/40 + 60x - 11700 + 27000x - 48 = 194

Combine the x terms: 60x + 27000x = 194 + 27/40 + 11700 + 48

Combine constants on the right side: 27060x = 194 + 27/40 + 11700 + 48

Combine the constants on the right side further: 27060x = 12194 + 27/40

Now, divide both sides by 27060 to solve for x: x = (12194 + 27/40) / 27060

You can calculate the numerical value of x by evaluating the expression on the right side.
