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

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
