Determine which equation shows if it could be a correct first step to solving the equation 3 (r + 8) = 42

a. r = 8 = 14
b. (3 * r) + (3 * 8) = 42
c. 3r + 8 = 42
d. 3 (r + 8) = 126
e. 3r + 24 = 42
f. r + 24 = 42

determine if these will work or if they wont work or if there is not enough info (which ones)

A. Not enough information given to solve (two equal signs not correct)
B. Will work, they distributed and then can easily be solved
C. Wont work. They distribute incorrectly and wrong answer would be given
D. Wont work. Not sure where the random 126 came intovthe eqation.
E. Will work. If they can easily do mathvin the head they know to multiply 3*8.
F. Will not work, the 3 disapears and wrong answer would be given

I hope this helps!

I think E could be match in order to Solve the equation : 3(r+8)=42finally,to solve it in order to find r that'll be 3r+24=42,sooo 3r=42-24,,,s 3r=18,,, so dividing both sides by 3,,,sooo r= 6

I'm not sure but i think it's 1670km/h
