Answer 1

300-78:x=287
78:х=300-287
78:х=13
х=78:13
х=6

Answer 2

To solve the equation (300 - 78/x) = 287, we need to isolate the variable x. Here's the step-by-step solution:

Step 1: Move the constant term to the other side of the equation.

Subtract 287 from both sides: 300 - 78/x - 287 = 287 - 287 300 - 78/x - 287 = 0

Step 2: Combine like terms on the left side.

13 - 78/x = 0

Step 3: Move the constant term to the other side again.

Subtract 13 from both sides: 13 - 78/x - 13 = 0 - 13 -78/x = -13

Step 4: Solve for x.

To solve for x, we need to isolate it on one side of the equation. Since -78 is multiplied by x, we can solve for x by dividing both sides by -78:

(-78/x) / -78 = (-13) / -78

x = 13/78

Therefore, the solution to the equation is x = 13/78.
