To solve the system of equations by substitution, we can substitute the expression for y from the second equation into the first equation.Given:
Substitute the expression for y from the second equation into the first equation:
Now, solve for x:
Now that we have the value of x, we can substitute it back into either of the original equations to find the value of y. Let's use the second equation:
Therefore, the solution to the system of equations is:
