The formula is P = E/t, where P means power, E means energy, and t means time in seconds. This formula states that power is the consumption of energy per unit of time.

Example Rearrange y =11+7x to make x the subject. Solution Starting from y =11+7x we subtract 11 from each side to give y ? 11 = 7x. Then, dividing both sides by 7 gives y ? 11 7 = x. Finally x = y ? 11 7 .

To rearrange an equation so that another variable becomes the subject, perform the same operations on both sides of the equals sign so that eventually this variable is by itself on the left hand side. Performing the same operations on both sides makes sure that the left hand side is always equal to the right hand side.

And to get rid of the 3 we justMoreAnd just subtract 4 from both sides. Giving us y minus 4 equals 3x. And to get rid of the 3 we just divide both sides by 3. But importantly it's the whole of the y minus 4 that we're dividing by 3.

So the answer is just x is equal to y minus.

You can also use multiple formulas in one cell by using the "&" operator. This operator allows you to join multiple formulas together and the formula will be evaluated from left to right. For example, the formula =A1&" "&A2 will join the value of A1 and A2 with a space in between.

No, you cannot have two formulas in one cell of Microsoft Excel. Each cell can contain only one formula. However, you can nest one formula inside another to achieve a desired result.

In other words, if you move a term from one side of the equals sign to the other, change the operation to do the opposite. (The opposite of an operation is called its inverse). For example, if the term you want to move is adding then when you move it to the other side it subtracts.
