Jane earns $41 more a week than twice as much as Bill does. Together they earn $140. How much does each earn....

J = 2(B) + 41

J + B = 140

J + B = 140

[quotebe8639db21="J4320"]J = B + 41

J + B = 140

Those are the two equations you need. )[/quotebe8639db21]

You mean

J=2B+41

J+B=140

J + B = 140

How could the cost be more than the selling price? lol
