Gsolve the equation, and check the solution. r plus 7 equals 9r+7=9 the solution set is startset nothing endset . (type an integer or a fraction.)

... r + 7 = 9

... r

Subtract 7 from both sides of the equation.

... r + 7 - 7 = 9 - 7

... r = 2 . . . . . . simplify

Expressed as a solution set, this may look like ...

... r ∈ {2}

You probably had no trouble solving this in 2nd grade when it was shown to you in the form ...

__ + 7 = 9
