IM ON A TIMED TEST PLEASE HELP ME The system of equations {4x+6y = 24 2x+y=8 has exactly one (x, y) pair for its solution.
Part A. If we double each side f the 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 with hanger diagrams, or by inventing a situation that the equations represent. Part B. If we add the two equations in the original system, we have 6x+7y=32. Explain why the same (x, y) pair is also a solution to this equation. Again you can support your explanation with diagrams or a situation, if needed

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784
