Question

What is the solution to the system of equations shown below?

2x + 5y + 3z = 10
3x ­ - y + 4z = 8
5x - ­ 2y + 7z = 12

a(7, 1, ­-3)
b(7, ­-1, ­-3)
c(7, 1, 3)
d(­-7, 1, -­3)

Answer 1

Explanation:

____

Good evening ,

_______________

2(7) + 5(1) + 3(-3) = 10

3(7) ­ - (1) + 4(-3) = 8

5(7) - ­ 2(1) + 7(-3) = 12

Then (7,1,-3) is a solution to system
