-10=-2c+5
Multiply both sides of the equation by 5.
-2c+5=-10
Swap sides so that all variable terms are on the left hand side.
-2c=-10-5
Subtract 5 from both sides.
-2c=-15
Subtract 5 from -10 to get -15.
c=\frac{-15}{-2}
Divide both sides by -2.
c=\frac{15}{2}
Fraction \frac{-15}{-2} can be simplified to \frac{15}{2} by removing the negative sign from both the numerator and the denominator.
