First you add the 1/4 and 3/4 together forgetting the /4 and adding the 1+3, that makes 4/4 which is a 1 then add that 1 to the 1 and 2 left over to get the answer
For this case we must solve the following system of equations:

We multiply the first equation by -2:

We add the new equation with the second one:

We have different signs subtracted and the sign of the major is placed:

Now we find the value of the variable "y":

Thus, the solution of the system is given by:
