Answer:
Subtract from both sides of the equation the term you don't want
Step-by-step explanation:
In solving equations, you generally want to "undo" operations that are done to the variable. Addition is "undone" by adding the opposite (that is, subtracting the amount that was added). Multiplication is "undone" by division.
If you have variables on both sides of the equation, pick one of the variable terms and subtract it from both sides of the equation.
<u>Example</u>
2x = x +1
If we choose to subtract x, then we will have a variable term on the left and a constant term on the right:
2x -x = x -x +1 . . . . . . . x is subtracted from both sides
x = 1 . . . . . . simplify
__
Note that we purposely set up this example so that removing the variable term from the right side caused the variable term and constant term to be on opposite sides of the equal sign. It may not always be that way. As long as you remember that an unwanted term can be removed by subtracting it (from both sides of the equation), you can deal with constant terms and variable terms no matter where they appear.

<em>Additional Comment</em>
It usually works well to choose the variable term with the smallest (or most negative) coefficient. That way, when you subtract it, you will be left with a variable term that has a positive coefficient.
Answer:
A): 22/5 = 4 2/5 in mixed fraction. 22/5 = 4.4 in decimal. B): 0.875
Step-by-step explanation:
Since you can't divide 7/8 it will turn into decimal. If you use calculator, it will be decimal. Basically in order to do long division, you would need to drop down zeros like add zeros if the divisor and dividend don't equal. You keep adding zeros until it's equal. IF it is more likely to be continuous, then you would need to add a repetend on the last digit. For example, 3/1 you can know it would be 1.333333 and so on. Example of how to do it:
