Step 1: To solve by substitution, we'd have to get a variable by itself so that we can plug it into the other.
Let's try to get 'x' by itself on the left equation to make it easier, since it doesn't have a number already attached to it.
Step 2: Add '3y' to both sides to get 'x' by itself
Step 3: We now have 'x' by itself and can plug it into the other equation to give us what 'y' is.
Plug in the above into the other equation.
Step 4: Distribute the '3' to everything in the parenthesis
Step 5: Combine like terms
Step 6: Continue combining like terms.. subtract 9 to both sides to get '14'y by itself
Step 7: Divide '14' to both sides to get 'y' by itself
We now know that the 'y' point to this system of equations is
With the 'y' point, you can find the 'x' by plugging in the 'y' to any of the two given equations.
I'm going to use this equation to make it easier
Step 1: We know what 'y' is, so plug into the equation to get the 'x' point
Step 2: Simplify
Step 3: Subtract '6' to both sides to get 'x' by itself
We now know that the 'x' point to this system of equations is
The solution is and
