7x+3=35x
Multiply both sides of the equation by 5.
7x+3-35x=0
Subtract 35x from both sides.
-28x+3=0
Combine 7x and -35x to get -28x.
-28x=-3
Subtract 3 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-3}{-28}
Divide both sides by -28.
x=\frac{3}{28}
Fraction \frac{-3}{-28} can be simplified to \frac{3}{28} by removing the negative sign from both the numerator and the denominator.
