WE 're saying negative 3/4 times some number x is equal to 10./13.IF. You said 5x equals 20, instead of dividing by 5,. We could

by 5 is 4, and we would have solved it.. WE multiply both sides by
the coefficient on x. The coefficient is the number that's being
multiplied by x. So. What 's the reciprocal of minus 3/4. Well, it 's
minus 4/3 times, and dot is another way to use times. The main
