I am going to assume by simplify you mean find the value of x. I am also assuming that the variable x is being multiplied by the denominator not the entire fraction from the way you wrote it.
-15/35x -7 = 0 set up the initial equation
-15/35x = 7 add 7 to both sides
-15 = 245x multiply both sides by 35x
-15/245 = x divide both sides by 245
-3/49 = x simplify the fraction
Just because I am unsure about how the equation that you posted is set up I will solve it assuming that the equation is (-15/35)x - 7
(-15/35)x - 7 = 0 set up the initial equation
(-3/7)x - 7 = 0 simplify the fraction
(-3/7)x = 7 add 7 to both sides
x = -49/3 multiply both sides by -(3/7)
