The system of equations {4x+6y=24
{2x+y=8

has exactly one (x, y)
pair for its solution.

a. If we double each side of the second equation, 2x+y=8,
we have 4x+2y=16.
Explain why the same (x, y)
pair that is the solution to the system is also a solution to this new equation. If needed, you can support your explanation by inventing a situation that the equations represent.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

answer4 to the second power is 16

and 4 to the third power is 64,
