How to slove with systems of equations

Answer:$3 for Syd and $5 for MarkStep-by-step explanation:when Mark worked 8 hours and Syd worked 10 hours they earned $80when Mark worked 9h Syd worked 5h they earned $65we can make a equation out of these information 8M + 10S = $809M + 5S = $65 we can use the systems of equations by eliminating method multiply second equation by -2-2 × (9M + 5S) = $65-18M - 10S = -$130 now add up the new equation with the first one8M + 10S - 18M - 10S = $80 - $130 (10S will eliminate -10S)-10M = -$5010M = $50M = $5 we can use hourly rate we found for M (Mark) to find the hourly rate for S (Syd)9×5 + 5S = $6545 + 5S = $655S = $15S = $3
