Draw the number line of 5 by 7, 8 by 3 - 23 by zero 1.3 - 2.3​

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

it would rotate about 180 degrees.

the answer is "add 2y and y"

step-by-step explanation:

you need to collect the like terms first.

the answer is: -22 also a
