Question

5x-15×(x-20)=900 sagyn6aeva_07

Answer 1

5x - 15(x - 20) = 900

5x - 15x + 300 = 900

- 10x = 900 - 300

- 10x = 600

x = 600 : (- 10)

x = - 60

Answer 3

To solve the equation 5x - 15(x - 20) = 900, follow these steps:

1. Distribute the -15 on the left side of the equation:

   5x - 15x + 300 = 900

2. Combine like terms on the left side of the equation:

   (5x - 15x) + 300 = 900 -10x + 300 = 900

3. Subtract 300 from both sides of the equation to isolate the variable term:

   -10x + 300 - 300 = 900 - 300 -10x = 600

4. Now, divide both sides by -10 to solve for x:

   (-10x) / (-10) = 600 / (-10) x = -60

So, the solution to the equation is:

x = -60
