Emily is solving the equation 2(x+9)=4(x+7)+2. Her step are shown. Click on the first step in which Emily made an error.

A. Step 1: 2(x+9)=4(x+7)+2
B. Step 2: 2x+18=4x+28+2
C. Step 3: 2x+18=4x+26
D. Step 4: -8x=2x
E. Step 5: -4=x

Also explain why answer B is wrong. <3

C. Step 3: 2x + 18 = 4x + 26

Step-by-step explanation:

Step 1: Write equation

2(x + 9) = 4(x + 7) + 2

Step 2: Solve for x

Here we see that Emily made a mistake here. Instead of adding 2 to 28 and getting 30, Emily subtracted 2 from 28 to get 26. Hence, our answer should be C.

f is the midpoint of

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
