1. Write all the equations in standard form, leaving out decimals or fractions.
2. Select the variables to be eliminated; And then you take two of these equations, and you eliminate the variables.
3. Select a different set of two equations and eliminate the same variables as in step 2.
4. Solve two equations containing two variables from steps 2 and 3.
5. Substitute the answer to step 4 into any equation that contains the remaining variables.
6. Check the solution with three original equations.
The answer is the third one. Trust me. I don't feel like explaining.
Step-by-step explanation:
X^2 + 9x + 20
x 5
x 4
(x + 5)(x +4)
x = -5,-4
hope this helps
