In a darts competition, Susan scored 147 more than John and three times as
much as Elizabeth. If their combined score came to 336 find their individual
scores.

>>...Susan scored 147 more than John...<<

S = J + 147

>>...Susan scored...three times as much as Elizabeth...<<

S = 3E

>>...their combined score came to 336...<<

S + J + E = 336

This gives us this system of equations:


S = J + 147
S = 3E
S + J + E = 336

Can you solve that system?  If not re-post.

Answers are S = 207, J = 60, E = 69
