Question

Steven is solving the equation 3(8−2x)+40=34. He begins with the following two steps.

Step 1: 3(8)+3(−2x)+40=34

Step 2: 24−6x+40=34

Which of the following is the best next step for Steven to take in solving the equation?

Question 4 options:

Multiply both sides by –6.


Add 24 and 40.


Add 24 to both sides.


Add 24 and 34.

Answer 1

Answer:

Add 24 and 40

Step-by-step explanation:

3(8 - 2x) + 40 = 34       use the distributive property a(b + c) = ab+ ac

3(8) + 3(-2x) + 40 = 34

24 - 6x + 40 = 34          combine like terms

-6x + (24 + 40) = 34      Answer: Add 24 and 40

-6x + 64 = 34            subtract 64 from both sides

-6x = -30          divide both sides by (-6)

x = 5

Answer 2

Answer:

Add 24 and 40.

Step-by-step explanation:

Steven is solving the equation $3(8-2x)+40=34$

Step 1:

$3(8)+3(-2x)+40=34$

Step 2:

$24-6x+40=34$

So, according to pemdas, the next step is Add 24 and 40.

Then this becomes:

Step 3:

$64-6x=34$

So, the answer will be option 2: Add 24 and 40.
