0.3x-0.5-0.4x=1
Subtract 0.4x from both sides.
-0.1x-0.5=1
Combine 0.3x and -0.4x to get -0.1x.
-0.1x=1+0.5
Add 0.5 to both sides.
-0.1x=1.5
Add 1 and 0.5 to get 1.5.
x=\frac{1.5}{-0.1}
Divide both sides by -0.1.
x=\frac{15}{-1}
Expand \frac{1.5}{-0.1} by multiplying both numerator and the denominator by 10.
x=-15
Fraction \frac{15}{-1} can be rewritten as -15 by extracting the negative sign.
