Question

4. Gavin and Seiji both worked hard over the summer. Together, they earned a total of $425. Gavin earned $25 more than Seiji. How much did each of them earn?

Answer 1

x = Gavin
y = Seiji

x + y = 425

Gavin earned $25 more than Seiji

x = (y + 25)

(y + 25) + y = 425

Solve the equation for y, which is Seiji.

Answer 2

Answer 3

Once you get the answer for y (Seiji), put the answer for y (Seiji) into this equation

x = Gavin
x = y + 25
