What is the answer to this equation: 7.4 - 9 - 2r =18

The answer to the equation is r=-9.8

First combine the like terms of the equation.

7.4-9-2r=18

7.4+(-9)=-1.6

-1.6-2r=18

Continue by adding 1.6 to both sides of the equation to isolate the variable.

-1.6-2r=18

+1.6 +1.6

-----------------

-2r=19.6

Divide -2 on both sides.

=

r=-9.8
