Why would you use addition to solve a subtraction equation?
because you undo the operation in the equation= to undo subtraction you add
How do you use inverse opperationto solve an equation or an inequality?
You need to isolate the variable you want to solve for, on one side of the equation. This involves getting rid of everything else. Note that what you do on one side of the equation, you also have to do on the other side. "Getting rid" of everything else basically means doing the inverse of the operation shown. Example: 2x + 3 = 21 You might start by getting rid of the 3. For this, you subtract 3 on both sides. Subtracting 3 is the inverse of the operation shown in the equation, adding 3. 2x + 3 - 3 = 21 - 3 2x = 18 Next, you get rid of the 2. Once again, since in the equation there is a multiplication by 2, you divide by 2 - the inverse operation. In this case, you divide by 2 on each side: 2x/2 = 18/2 (2/2)x = 18/2 x = 9
What are the steps to solve a whole number equaiton?
To solve a whole number equation, follow these steps: Simplify both sides of the equation by combining like terms. Use inverse operations to isolate the variable on one side of the equation. Perform the necessary operations to solve for the variable. Check your solution by substituting the value back into the original equation to ensure it satisfies the equation.
Which property would be use to isolate the variable j in this equation 7j equals 49?
You would use several properties. The first is that performing the same operation to both sides of an equation is valid. Next the multiplicative inverse property of 1/7 (with respect to 7).
Use any operation besides addition and subtraction to solve this equation 8 8 8 8 8 equals 9.?
This is not an equation. (8/8) times (8 and 8/8) = 9
