Answer :

2/3 x + 15 = 17
2/3 x = 17 - 15
2/3 x = 2
x = 2 / (2/3)
2/1 * 3/2 = 6/2 = 3
x = 3
So
2\3x+15=17                        FIRST SUBTRACT 15 FROM BOTH SIDES!!!!
       -15=-15                      =15 AND -15 CANCEL EACH OTHER AND 17-15=2
2\3x=2                              THEN DIVIDE BOTH SIDE BY 2\3x
÷2\3x=÷2\3x                      2\3 = 0.6666667
                         2\3x and 2\3x cancel each other and 2\0.6666667 = 0.33333333
                        
Answer would be rounded to nearest tenths
