Question

tell whether the system has one solution, infinitely many solutions, or no solution. x = -7y + 24 x + 7y = 32

Answer 1

This system has no solution.
x = -7y + 24 can be rewritten as x = 24 - 7y
to simplify x + 7y = 32, we have to subtract 7y from both sides
x = 32 - 7y
Now, our system is as follows:
x = 24 - 7y
x = 32 - 7y
