1.8=6.3+0.07x
Add 0.9 and 0.9 to get 1.8.
6.3+0.07x=1.8
Swap sides so that all variable terms are on the left hand side.
0.07x=1.8-6.3
Subtract 6.3 from both sides.
0.07x=-4.5
Subtract 6.3 from 1.8 to get -4.5.
x=\frac{-4.5}{0.07}
Divide both sides by 0.07.
x=\frac{-450}{7}
Expand \frac{-4.5}{0.07} by multiplying both numerator and the denominator by 100.
x=-\frac{450}{7}
Fraction \frac{-450}{7} can be rewritten as -\frac{450}{7} by extracting the negative sign.
