Question

2. At a gym, Frank did a certain number of

push-ups. Tom did 12 more than Frank.
The total number both men did was 66. Which
equation could be used to find the number of
push-ups Frank did?
A. X + 12x = 66
B. 2x + 12 = 66
C. 2x = 66 + 12
D. x + 12 = 66 +
X
D​

Answer 1

B

Frank did x push up, and Tom did 12 more than him. The original equation would be:

x+x+12=66

[Frank's pushups]+[Frank's pushups plus Tom's]=[Total]
