Question

What is -2(5+6n)<6(8-2n)

Answer 1

-2(5+6n)<6(8-2n)
-10-12n<48-12n
-12n+12n<48+10
0<58
Therefore, as 0<58, and this is true, this equation is correct for all value of x, that is to say, "x" can take any value.

Solution: (-∞,+∞)

This is the order that you do to solve the problem, For example,
P stands for Parentheses
E stands for Exponents
M stands for Multiplication
D stands for Division
A stands for Addition
S stands for Subtraction
This is the order of how you solve the problem. If one of the things aren't in the particular problem, then skip that certain step. For example if Addition wasn't in the problem, then you would skip the A. I hope this helps!
