Elimination is where you aline two equations with the varibles in the same place and the second equation substracts the first equation. Important to know that in the second equation all varibles and constant or y - intercepts are negative. Now with this just start with the first two equations, 5x + 2y -3z = 10 and 2x - 2y + 4z = 6.

5x + 2y - 3z = 10

- 2x + 2y - 4z = -6

3x + 4y - 7z = 4

Do the same thing with the last equation.

3x + 4y - 7z = 4

-x + y - 2z = -3

2x + 5y -9z = 1

Please tell me if I got it wrong, but from what I concluded there's no solution.

Answer:

the margin of error is 0.05

Step-by-step explanation:

Margin of error = confidence interval ÷ 2

MOE = CI ÷ 2

Confidence interval CI = 0.2 - 0.1 = 0.1

MOE = CI ÷ 2 = 0.1 ÷ 2 = 0.05

the margin of error is 0.05
