2\times 7-5\times 3=10w
Variable w cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 10w, the least common multiple of 5w,2w.
14-15=10w
Do the multiplications.
-1=10w
Subtract 15 from 14 to get -1.
10w=-1
Swap sides so that all variable terms are on the left hand side.
w=\frac{-1}{10}
Divide both sides by 10.
w=-\frac{1}{10}
Fraction \frac{-1}{10} can be rewritten as -\frac{1}{10} by extracting the negative sign.
