Can someone help me? Solve the following simultaneous equation:
x + 2y - z = 2
3x - y + 2z = -3
2x + 3y + z = 5

x = -1, y = 2, z = 1

Explanation:

* note

we will solve the simultaneous equation using the Gaussian Elimination

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
