Solve the following system of equations

Question

x plus 7y=2 (1)

x=4 minus 7y (2)

Answer 1

Let's plug equation (2) into (1) to get

(4 - 7y) + 7y = 2

4 = 2   <--not true

plugging (1) into (2)

first I try solving for x

(1)  x + 7y = 2

      x = 2 - 7y

(2)  2 - 7y = 4 - 7y

      2 = 4  <-- not true

next I will try y...

(1)  x + 7y = 2

      7y = x - 2

      y = (x - 2) / 7

plugging into (2)

x = 4 - 7(x - 2)/7

x = 4 - (x - 2)

x = 2 - x

2x = 2

x = 1

now plug back into either (1) or (2), and solve for y

however you get inconsistent values for y

leading me to believe the answer is "no solution" or this is copied wrong..

Answer 2

These equations are either incorrectly copied or they are inconsistent (system of) equations.

Answer 3

no solution..
