1440= 3/50 x+3/40 (20000-x)

1440 = \frac{3}{50} x + \frac{3}{40} (20000 - x)

x = 4000

Solution steps

1440 = \frac{3}{50} x + \frac{3}{40} (20000 - x)

Switch sides

\frac{3}{50} x + \frac{3}{40} (20000 - x) = 1440

Multiply by LCM

12 x + 15 (20000 - x) = 288000

Expand

12 x + 15 (20000 - x) : - 3 x + 300000

- 3 x + 300000 = 288000

Move

300000

to the right side

- 3 x = - 12000

Divide both sides by

- 3

x = 4000

x, - x + y = 6

3 x + 2 = 4 x

- \frac{1}{4} (x - 12) = 24

\frac{3}{5} x = - 6

y = \frac{1}{2} (- 2)
