Solve the system
9x-5y=119
18x-10y=238
Double both sides of the first equation and you have
18x-10y =238
which is the same as the second equation. Since the two equations are not independent, there are no unique solutions. Thee are an infinite number of pairs of x and y that will work.
To solve the system of equations, you can use the method of elimination or substitution. Let's use the method of elimination.
Step 1: Multiply both sides of the first equation by 2 to make the coefficients of x equal in both equations.
2(9x - 5y) = 2(119)
18x - 10y = 238
Step 2: Now we have the same equation for both equations, so they are dependent, and there are infinitely many solutions.
This means any value of x and y that satisfies the equation 18x - 10y = 238 will be a solution to the system of equations.
So, there is no unique solution for the given system.
