1/8x = -5
isolate the x, remember that what you do to one side, you do to the other (because of equal sign)
1/8x(8) = -5(8)
x = -5(8)
x = -40
Note: two positive numbers multiplied or divided = positive answer. One negative and one positive number multiplied or divided = negative answer. Two negative numbers multiplied or divided = positive answer
hope this helps
