Substitute the given value of x into the first equation

To solve for x distribute 3 though the parentheses

Collect like terms

Move the constant to the right-hand side and change its sign

Add the numbers

Divide both sides of the equation by 13

Now, Substitute the given value of x into the second equation

Plug in the value of x in the equation i.e. 1

Any number multiplied by 1 results in number itself

Calculate the difference

The possible solution of the system is the ordered pair (x,y)
