Help with number 7 please just real answers tell me how you got the answer. I’ll appreciate it.

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
