10x+1.5\times 6x+2400=30900
Multiply 2.5 and 4 to get 10.
10x+9x+2400=30900
Multiply 1.5 and 6 to get 9.
19x+2400=30900
Combine 10x and 9x to get 19x.
19x=30900-2400
Subtract 2400 from both sides.
19x=28500
Subtract 2400 from 30900 to get 28500.
x=\frac{28500}{19}
Divide both sides by 19.
x=1500
Divide 28500 by 19 to get 1500.
