Solve for a, b and c given that:
- 2a+4b+5c= 2
- 5a+3b-2c= 13
- 3a-2b-3c= 0
One way is called the substitution method. Pick any one of the equations, say the bottom one, and solve it for one of the variables:
Insert this value of c into the other two equations:
So now we need to solve:
Solve one of these for one of the other unknowns, etc.
For verification I get that
