4\times 3=x\times \frac{14}{0.875}
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 4x, the least common multiple of x,4.
12=x\times \frac{14}{0.875}
Multiply 4 and 3 to get 12.
12=x\times \frac{14000}{875}
Expand \frac{14}{0.875} by multiplying both numerator and the denominator by 1000.
12=x\times 16
Divide 14000 by 875 to get 16.
x\times 16=12
Swap sides so that all variable terms are on the left hand side.
x=\frac{12}{16}
Divide both sides by 16.
x=\frac{3}{4}
Reduce the fraction \frac{12}{16} to lowest terms by extracting and canceling out 4.
