What is the solution to 7x plus y plus z equals 6 7x plus y plus 4z equals 9 y plus x equals 6?
7x + y + z = 6
7x + y + 4z = 9
y + x = 6
Take the first two statements and subtract them.
7x + y + z = 6
7x + y + 4z = 9
_____________
0 + 0 - 3z = -3
Therefore: z = 1
Then you are left with:
7x + y + 1 = 6
7x + y + 4 = 9
which is impossible, so this is an impossible equation.
