Which is the correct estimation and justification for the problem shown below?
v10 = ?
about 5, because 2 x 5 = 10
about 5, because 5 + 5 = 10
about 4, because 4 x 4 = 16
about 3, because 3x3 = 9

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

1/3 + 1/5 = 8/15.
