Ana and amy start a landscaping job together. when ana stopped, she completed 2/5 of the job. when amy stopped, she completed 1/3 of the job

I assume the question is to calculate how much work is left to complete.

we know that

the 100% of the work is equal to 1

so

To find how much work is left to complete

therefore

the work completed is equal to

the pending work to be completed is

the total work  is equal to

207/8 is the right

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
