9.8=x\times 0.98
Multiply 49 and 0.2 to get 9.8.
x\times 0.98=9.8
Swap sides so that all variable terms are on the left hand side.
x=\frac{9.8}{0.98}
Divide both sides by 0.98.
x=\frac{980}{98}
Expand \frac{9.8}{0.98} by multiplying both numerator and the denominator by 100.
x=10
Divide 980 by 98 to get 10.
