Question

What are all of the steps to get 7(3x-1)-(x+5)

Answer 1

Answer:

20x-12

Step-by-step explanation:

Given:

7(3x−1)−(x+5)

Step 1: Distribute the Negative Sign:

=7(3x−1)+−1(x+5)

=7(3x−1)+−1x+(−1)(5)

=7(3x−1)+−x+−5

Step 2: Distribute:

=(7)(3x)+(7)(−1)+−x+−5

=21x+−7+−x+−5

Step 3: Combine  

=21x+−7+−x+−5

=(21x+−x)+(−7+−5)

=20x+−12

Answer 2

Answer:

Check description

Step-by-step explanation:

Remember, P.E.M.D.A.S. Parenthesis first so 3x-1 and x+5. Not given enough information, I cannot give you the correct answer so instead, I will give you the equations you will have to do and these are not all in the order of what you have to do, but most of them are. Just follow P.E.M.D.A.S. if you know what to do. (I will put letters as answers)

step 1: (3x-1)

3 times x = Q

Q minus 1 = P

step 2: (x+5)

x plus 5 = E

step 3: 7xP

7 times P = W(The one from step 1)

step 4: W-E

W-E= A
