Jorge asked 15 of his classmates how many different states they have lived in. The results are shown in the dot plot. Which of the following statements is true?

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

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

but which class are u may know that first
