1.5x+0.05-1.45x=-0.05
Subtract 1.45x from both sides.
0.05x+0.05=-0.05
Combine 1.5x and -1.45x to get 0.05x.
0.05x=-0.05-0.05
Subtract 0.05 from both sides.
0.05x=-0.1
Subtract 0.05 from -0.05 to get -0.1.
x=\frac{-0.1}{0.05}
Divide both sides by 0.05.
x=\frac{-10}{5}
Expand \frac{-0.1}{0.05} by multiplying both numerator and the denominator by 100.
x=-2
Divide -10 by 5 to get -2.
