How can you solve an equation or inequality in one variable?

Mathematics

In order to solve an equation for a variable, we need to isolate that variable on one side of the equation (either left side or right side).

Following are some steps to solve equation/inequality in one variable:

1) Get rid constant number from on side by applying reverse operation of addition or subtraction.

2) Get rid variable terms from other side by applying reverse operation of addition or subtraction.

3) Combine like terms on both sides.

4) Get rid any coefficent ( a number in front of a variable) by dividing from both sides.

5) Finally you get a variable on one side and solution on other side.

Which of the following is equal to 20x + 8y - 80?

It would be C because if you take out the four, the coefficients are multiples of 4 so it simplifies down.

Stephanie makes $6.60 an hour plus tips working at a restaurant. On a particular day, she worked 8 hours and made $78.80. Write
aleksandr82 [10.1K]
Here is what'd you do:

Ignore the $78.80 at the moment and focus on the $6.60 an hour and she worked 8 hours.

So, basically you'd do 6.60 * 8 (or 660*8 if you aren't allowed a calculator)

For 660*8 you'd get:
5280. move the decimal over twice.

$52.80 , if you are allowed a calculator you would have just done 6.60 * 8

So now you know she got $52.80 just working hourly.

Subtract $78.80 from $52.80

Your Answer:
Stephanie made $26 from tips.
