Tony pays $6.75 for his item, & Tanya pays $9 for her items

Step-by-step explanation:

Let Tanya's item be x, and Tony's be y. Set the system of equality:

3x = 4y

y = x - 2.25

Plug in x - 2.25 for y in the first equation

3x = 4(x - 2.25)

Distribute 4 to all terms within the parenthesis

3x = 4x - 9

Isolate the x. Subtract 4x from both sides

3x (-4x) = 4x (-4x) - 9

3x - 4x = -9

-x = -9

Isolate the x. Divide -1 from both sides

(-x)/-1 = (-9)/-1

x = 9

Plug in 9 for x in the equation

y = x - 2.25

y = (9) - 2.25

y = 6.75

Tony pays $6.75 for his item, & Tanya pays $9 for her items
