x\sqrt{4}+5=105x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
x\times 2+5=105x
Calculate the square root of 4 and get 2.
x\times 2+5-105x=0
Subtract 105x from both sides.
-103x+5=0
Combine x\times 2 and -105x to get -103x.
-103x=-5
Subtract 5 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-5}{-103}
Divide both sides by -103.
x=\frac{5}{103}
Fraction \frac{-5}{-103} can be simplified to \frac{5}{103} by removing the negative sign from both the numerator and the denominator.
