Which of the following is the solution set of 18 - 3n + 2 = n + 20 - 4n?

The solution set is the set of all real numbers.

Step-by-step explanation:

Solve:

Like terms are those terms which have same variable to the same power:

Combine like terms;

Subtract 20 from both sides we get;

Simplify:

Add 3n to both sides we get;

Simplify:

for all n

Thus, the given system is dependent.

Therefore, the solution set is set of all real numbers.

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

the answer is 99.
