0.04x+0.045(12000-x)=525

0.04 x + 0.045 (12000 - x) = 525

x = 3000

Solution steps

0.04 x + 0.045 (12000 - x) = 525

Multiply both sides by

1000

40 x + 45 (12000 - x) = 525000

Expand

40 x + 45 (12000 - x) : - 5 x + 540000

- 5 x + 540000 = 525000

Move

540000

to the right side

- 5 x = - 15000

Divide both sides by

- 5

x = 3000

6 x^{2} - 9 = 0

(x - 7)^{2} + 6 = 0

\frac{52 !}{( 52 - 2 ) ! 2 !}
