3\left(1-x\right)=5\left(1-0.7\right)
Multiply both sides of the equation by 75, the least common multiple of 25,15.
3-3x=5\left(1-0.7\right)
Use the distributive property to multiply 3 by 1-x.
3-3x=5\times 0.3
Subtract 0.7 from 1 to get 0.3.
3-3x=1.5
Multiply 5 and 0.3 to get 1.5.
-3x=1.5-3
Subtract 3 from both sides.
-3x=-1.5
Subtract 3 from 1.5 to get -1.5.
x=\frac{-1.5}{-3}
Divide both sides by -3.
x=\frac{-15}{-30}
Expand \frac{-1.5}{-3} by multiplying both numerator and the denominator by 10.
x=\frac{1}{2}
Reduce the fraction \frac{-15}{-30} to lowest terms by extracting and canceling out -15.
