solve the following system by the substitution method 3x+9y=2 x=7-3y
To solve the system of equations by substitution, we can substitute the value of x from the second equation into the first equation.
Substitute x = 7-3y into the first equation:
3(7-3y) +9y = 2
21 - 9y + 9y = 2
21 = 2
This equation is not true, meaning there is no solution to the system of equations.
