Answer 1

Let the first number be \(\Large\rm x\).
The number that comes after that would be \(\Large x+1\).

The sum of these two consecutive numbers is \(\Large\rm 73\).

\(\Large\rm x+x+1=73\)
Just need a single step to match one of your option from this point :)

Answer 3

\(\Large\rm .02x+.04(x+800)=92\)

This equation represents our interest ^
2% of the amount x,
4% of the amount x+800,
and it sums up to 92 dollars of interest.

Solving this equation gives us, \(\Large\rm x=1000\).
Which tells us the amount in the other account would be, \(\Large\rm x+800=1800\).
