-3/5 * x = 30

multiply both sides by 5 to get:

-3*x = 30*5

divide both sides by -3 to get:

x = 30*5/(-3)

solve for x to get:

x = -50

answer should be x = -50

plug into original equation to get:

-3/5 * x = 30 becomes:

-3/5 * -50 = 30

simplify to get:

-3 * -10 = 30

simplify further to get:

30 = 30

answer of -50 looks good.
