2.4\times 9=8.57-2x
Add 6 and 3 to get 9.
21.6=8.57-2x
Multiply 2.4 and 9 to get 21.6.
8.57-2x=21.6
Swap sides so that all variable terms are on the left hand side.
-2x=21.6-8.57
Subtract 8.57 from both sides.
-2x=13.03
Subtract 8.57 from 21.6 to get 13.03.
x=\frac{13.03}{-2}
Divide both sides by -2.
x=\frac{1303}{-200}
Expand \frac{13.03}{-2} by multiplying both numerator and the denominator by 100.
x=-\frac{1303}{200}
Fraction \frac{1303}{-200} can be rewritten as -\frac{1303}{200} by extracting the negative sign.
