Answer 1

Answer:

Step-by-step explanation:

An "x" should be with the 17/20. (With fractions in this form putting the variable with the numerator is more legible.)

 

3x/5 + 17x/20 + 6.5 = x  

12x + 17x + 130 = 20x        multiply both sides by 20

19x + 130 = 20x                  combine like terms

130 = x                                subtract 19x from both sides
