Question

Seiji and gavin both worked hard over the summer. Together they earned a total of $425. Gavin earned $25 more than seiji.

Answer 1

S + g = 425
g = s + 25...these 2 equations are ur system of equations

s + (s + 25) = 425
2s + 25 = 425
2s = 425 - 25
2s = 400
s = 400/2
s = 200 <== what Seiji earned

g = s + 25
g = 200 + 25
g = 225 <=== what Gavin earned
