murzikaleks [220]

Answer:

(0.7, -1)

M = ( $\frac{1.8 - 0.4}{2}, \frac{-3.4 + 1.4}{2}$ )

M = $(\frac{1.4}{2}, \frac{-2}{2})$

M = (0.7, -1)

Matt = 3 + 4x
Samantha = Matt
[x = Number of hours]

Solution:

15 + 2x = 3 + 4x
=> 15 - 3 = -2x + 4x
=> 12 = 2x
=> x = 6

Hence, after 6 hours of work, Samantha and Matt will have the same amount.
