Solve for x: 156.2 + 234.6 = 750x%

There is an error in the equation provided. The left side of the equation adds up to 390.8, not 390.8x as it should be in order to solve for x.

Assuming the equation is supposed to be:

'156.2 + 234.6 = 750x%'

We need to first convert the percentage to a decimal:

750x% = 7.5x (since 750% = 7.5)

Now we can solve for x:

156.2 + 234.6 = 7.5x

390.8 = 7.5x

x = 52.107

Therefore, 156.2 + 234.6 is equal to 52.107% of 750.

To verify this:

52.107% of 750 = (52.107/100) * 750 = 390.8
