To solve this problem, we need to pick numbers from the table then this number will be substituted into the equation. But first, we equate the numbers such as below: 4x - 2y = 8 Transpose -2y to the right side such as: 4x = 8 + 2y 4x - 8 = 2y (4x -8)/2 = y 2x - 4 =y From the table, let us choose x = 0 y = 2x -4 y = 2(0) -4 y = -4 From the table, let choose another value of x such as x=1 y = 2(1) -4 y = 2 - 4 y = -2
This will prove that the values in the table are correct.
