Vineet solved a system of equations by substitution. In his work, he substituted an expression for one of the variables and solv
ed for the value of the other. This resulted in the equation 7 = 9. What can Vineet conclude? The solution to the system is (7, 9).
The system of equations does not have a solution.
The work must be incorrect because it is not possible to get this equation.
The system of equations has infinitely many solutions.
Diana's age=21 years Carmen's age=x years Andrew's age=2x years 21+x+2x=45 21+3x=45 3x=45-21 3x=24 x=24/3 x=8 2x8=16 Carmen is 8 years old and Andrew is 16 years old. Hoped that helps:)
