Find three solutions of the equation y=7x

Step-by-step explanation:

You are given 2 variables. Plug in a number for one variable (the input variable), and get the answer (output variable).

Let: x = 5

Plug in 5 for x in the equation, and solve:

y = 7(x)

y = 7(5)

y = 35

When x = 5, y = 35

Let: x = 20

Plug in 20 for x in the equation, and solve:

y = 7(x)

y = 7(20)

y = 140

When x = 20, y = 140

Let: x = 39

Plug in 39 for x in the equation, and solve:

y = 7(x)

y = 7(39)

y = 247

When x = 39, y = 247.
