Solve the following equation:
First let's rewrite the expression as a fraction:
We should note that since there is only a multiplication operation in the numerator of the fraction, we will multiply the coefficients together:
\( 100-(5+55)= \)
When you have multiplication in the denominator like 2t·4z, you must multiply the numbers together: 2×4=8. The variables t and z stay as they are, giving you .
The · symbol means multiplication, so 2t·4z = 8tz. The + symbol means addition, so 2t+4z cannot be simplified further. Always pay attention to the operation!
In , you can only cancel if the same variable or number appears in both numerator and denominator. Here, x is only on top, while t and z are only on bottom, so no canceling is possible.
A fraction is simplified when:
The same rule applies! Multiply all the coefficients (numbers) together, then keep all the variables. For example: .
