There are infinitely many solutions of the system of equations, x + y = 1
and 2x + 2y = 2
Step-by-step explanation:
We need to find how many solutions are there to the system of equations.

Solving:
Multiply equation (1) with 2 and subtract with equation(2)

Since our answer is 0=0 so, there are infinitely many solutions.
