25-7x+2=0
Calculate 5 to the power of 2 and get 25.
27-7x=0
Add 25 and 2 to get 27.
-7x=-27
Subtract 27 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-27}{-7}
Divide both sides by -7.
x=\frac{27}{7}
Fraction \frac{-27}{-7} can be simplified to \frac{27}{7} by removing the negative sign from both the numerator and the denominator.
