Question

Is (1,-3) is a solution of the equation 8p-2q=14?

Answer 1

Answer: YES

Step-by-step explanation:

  8p - 2q = 14

8(1) - 2(-3) = 14

8   -    -6   = 14

 8    +   6  = 14

       14      = 14

            TRUE

Answer 2

(p, q) = (1, -3)

Plug in the corresponding numbers to the corresponding variable

8p - 2q = 14

8(1) - 2 (-3) = 14

Simplify. Remember to follow PEMDAS. First, multiply

8 x 1 = 8

-2 x -3 = 6

8 + 6 = 14

Finally, add

(8 + 6) = 14

14 = 14 (True)

Yes, (1, -3) is a solution for 8p - 2q = 14
