Collect like terms by calculating the sum or difference of their coefficients
(1−0.4)x
Subtract the numbers
0.6x
0.6x−30000=0
Move the constant to the right side
0.6x=0+30000
Removing 0 doesn't change the value,so remove it from the expression
0.6x=30000
Divide both sides
0.60.6x=0.630000
Divide the numbers
x=0.630000
