The equation that's been computed shows that the number of cell phones that his family can have will be 2.
<h3>How to solve the equation</h3>
From the question, it was stated that the cell phone company charges $50 plus $40 per line each month and that Luke must spend under $170 on his family's cell phone bill each month.
Let the number of cell phones that can be bought be represented by x.
The equation to solve the question will be:
50 + 40(x) < 170
50 + 40x < 170
Collect like terms
40x < 170 - 50
40x < 120
x < 120/40
x < 3
Therefore, the number of cell phones has to be less than 3. Hence, this will be 2.

Answer:
no solution
Step-by-step explanation:
We can think of an absolute value as the magnitude of the number. We can also define it as how far the number is from 0 on the number line. Thus, absolute value must always be positive (or 0).
<h3>
Solve</h3>
Start by adding 1 to both sides:

Multiply both sides by 2:

The absolute value of a number is always positive (with the exception of 0), therefore there is no solution.
<h3>Additional Comments</h3>
Notice we can only add/multiply (or subtract/divide) an equation because of the Addition/Subtraction/Multiplication/Division Property of Equality which state that if you add/subtract/multiply/divide one side of the equation by a certain value, you must do the same to the other side of the equation.
Idk, pick one of them, thats ur best bet
"n" is a variable, and it is often found in equations for accounting, physics and arithmetic sequences
