Answer:
Frank, you're wrong! x=x is a variable, where 12=12 is a specific number. x can represent any number, even 12. So Frank's answer is more general, whereas Sarah's answer is specific.
Explanation:
2(x+12)+6=3(x+6)+(12-x)
2x+24+6=3x+18+12-x
2x+30=2x+30
2x+30-30=2x+30-30
2x=2x
x=x, or...
2x-2x+30=2x-2x+30
30=30
the answer is C- "seeing ourselves as others see us would free us from blundering"
