Step-by-step explanation:

y=4x+360

y=10x+6x

i'll solve for x through elimination.

first combine like terms, y=10x+6x = y=16x

then subtract x from both equations.

y-4x=4x-4x+360 = y-4x=360

y-16x=16x-16x = y-16x=0

then rearrange the two equations by terms, y-y-4x+16x

solve, y-y=0, 16x-4x=12x

12x=360

divide both sides by 12.

x=30

sorry, i don't know i just need points, i'm new here. chao

i would say c is the best answer, hope it's right!

good luck! =)
