(PLEASE HELP)Solve the given system using your choice of either graphically or algebraically. Show and explain all work. y = 2x - 4
x + 2y = 12

algebraically.

y = 2x - 4…(1)

x + 2y = 12(2)

substituting the value of y in equation (2) we get

x+2(2x - 4)=12

x+4x-8=12

5x=12+8

x=20/5=4

substituting the value of x in equation(1) we get

y=2×4-4=8-4=4

:.(x,y)=(4,4)answer

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved

happy to
