Question

If y varies directly with x,and y is 14when x is 2,what is the value of x when y is 35

Answer 1

x=5

1) Since y varies directly with x, then we can write a table

x | y

2 14

35

2) Since y is 7 times the value of x, then we can state that

x | y

2 14

5 35

3) So this variation can be expressed as y=7x and x=5
