Guys it’s question 5 look at the photo please

I think :) :)

Step-by-step explanation:

If u have a mirror, put that on the line, it's easier

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
