Write a system of linear equation to model this situation. Describe what the variables
represent?

1,150 give brainliest

step-by-step explanation

2r= 2300

r =1150

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

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

according to egenuity the answer is
