Question

Use substitution to solve the system of equations. How many solutions are there?

12
x − 13
y = 5
x = 23
y + 10



There are no solutions.




There is one solution.




There are infinitely many solutions.




It is not possible to determine the number of solutions.

Answer 1

I can’t read the system as typed — the equations got jumbled. Could you retype them clearly, for example as one of these formats?

- 12x − 13y = 5
x = 23y + 10

- 12/(x − 13) = 5/(x) and x = 23/(y + 10)

- 12/(x − 13) − 13/(y) = 5
x = 23/(y + 10)

or simply put each equation on its own line, e.g.
12x - 13y = 5
x = 23y + 10

Once you send the correctly formatted system I’ll use substitution and tell you how many solutions there are (and give the solution if unique).
