Question

. Joyce and Marianne both earn a combined income of $1,600 a week. Marianne earns $200 more than Joyce. How much income do Joyce and Marianne each earn?

( I need the equation and it needs to be solved. )

Answer 1

So Joyce earns $700 and Marianne earns $900 per week. and $900=$200+$700. A slightly different approach is to say, if Marianne didn't earn 200 more than Joyce, then the combined income would be $200 less or $1600-$200=$1400. Now they both earn the same so each would get half of $1400 or $700.
