Assuming your equation is: -2/5n = -30 -2/5n = -30 <- We get rid of the "/5n " by multiplying each side by 5n -2 = -30 * 5n -2 = -150n -1 = -75n 75n = 1 But this doesn't match up with any of your answers, so if you wouldn't mind giving me the equation again, i'll work it out
two negatives make a positive, so the question is basically 2/5 x 30. 30/5 is 6, so 1/5 of 30 is 6. we want 2/5 so we double 1/5 and get 12. The correct answer is n.
