Answer:
The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.

Step-by-step explanation:
Writing the two equations in full and subtracting R(x) from W(x) to arrive at D (x) gives the answer. This is shown below;
W(x) = 0.002x^3 - 0.01x^2 + 0x + 0
R (x) = 0x^3 + x^2 - 4x +13 -
-----------------------------------------------
D(x) = 0.002x^3 -1.01x^2 + 4x - 13
Answer:
It would take 1.5 hours for all three to finish the work if they worked together.
Step-by-step explanation:
Elon and Jeff can complete the work in 3 hours.
Jeff and Bruce can complete the work in 6 hours.
Elon and Bruce can complete the work in 4 hours.
3 + 6 + 4 = 13
13 / 3 = 4.33
4.33 / 3 = 1.44
