-7x+3+1=0
Combine -3x and -4x to get -7x.
-7x+4=0
Add 3 and 1 to get 4.
-7x=-4
Subtract 4 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-4}{-7}
Divide both sides by -7.
x=\frac{4}{7}
Fraction \frac{-4}{-7} can be simplified to \frac{4}{7} by removing the negative sign from both the numerator and the denominator.
