We want to find x in times of y and z, so we want to have only 1 x on the LHS of equation, so
3x-7y=z      /+7z   (add 7z both sides)
3x=z+7z      /:3 (divide 3 both sides)
x= \frac{z+7y}{3} - its the result.

marissa [1.9K]
If she stopped at 8;05, and she started 20 minutes earlier, just imaging a clock at 8:05 and turn back time 20 minutes.

Five minutes would be 8:00, ten minutes is 7:55, fifteen minutes is 7:50, and twenty minutes is 7:45. This, she started at 7:45
