7+x=x\times \frac{4.126}{0.65}
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
7+x=x\times \frac{4126}{650}
Expand \frac{4.126}{0.65} by multiplying both numerator and the denominator by 1000.
7+x=x\times \frac{2063}{325}
Reduce the fraction \frac{4126}{650} to lowest terms by extracting and canceling out 2.
7+x-x\times \frac{2063}{325}=0
Subtract x\times \frac{2063}{325} from both sides.
7-\frac{1738}{325}x=0
Combine x and -x\times \frac{2063}{325} to get -\frac{1738}{325}x.
-\frac{1738}{325}x=-7
Subtract 7 from both sides. Anything subtracted from zero gives its negation.
x=-7\left(-\frac{325}{1738}\right)
Multiply both sides by -\frac{325}{1738}, the reciprocal of -\frac{1738}{325}.
x=\frac{-7\left(-325\right)}{1738}
Express -7\left(-\frac{325}{1738}\right) as a single fraction.
x=\frac{2275}{1738}
Multiply -7 and -325 to get 2275.
