Given the system of equations: 3x + 2y - 2 = 0 and 2x + 2y + 1 = 0. If x = 3 is substituted into the first equation, what is the value of y?

Consider the system of equations: 3x - 4y = 0 and 3x + 4y = -24. If the two equations are added together to eliminate y, what is the value of x?

For the system of equations 3x - 4y = 0 and 3x + 4y = -24, if x = -4, what is the value of y?

Given the system of equations: -2x + 3y = -13 and 2x + 4y = -8. If y = -3, what is the value of x?
