3x-2=28

OpenStudy (anonymous):

3x = 30

OpenStudy (anonymous):

x = 10

The object is to get the variable by itself to know what the variable is. 3x - 2 = 28 Add 2 to each side to cancel out the - 2. 3x = 30 Divide 3 from each side because right now 3 is technically being multiplied by x, so do the opposite. x = 10
