83100
Step-by-step explanation:
part A
y=nx
part B
y=48×x
y=48x
The two expressions are equivalent because they have the same value regardless of the number of substituted in for y
x should equal -2 and y should equal -3 to solve this i multiplied the first equation by 2 then got rid of the 4y and -4y then i added the 14x to the 9 equaling 23x and added the -40 to the -6 which became 23x=-46 i solved this getting -s for x, then i plugged that into the equations to get y which was -3
