Answer:
Step-by-step explanation:
The given equation is expressed as
x1 + 2x2 = -24- - - - - - - - --1
x1 + 7x2 = -11- - - - - - - --2
We would eliminate x1 by subtracting equation 2 from equation 1. It becomes
- 5x2 = - 13
Dividing both sides of the equation by - 5, it becomes
- 5x2/- 5 = - 13/- 5
x2 = 13/5
Substituting x2 = 13/5 into equation 2, it becomes
x1 + 7 × 13/5 = -11
x1 + 91/5 = - 11
x1 = - 11 - 91/5
x1 = - 146/5
