I dont know where to start, since the first and last equations dont have any similar terms, what strategy is there for this?
Hello, Nervous!
Where did this problem come from?
The equations are clumsily written.
First, I would eliminate the fractions, simplify, and write the equations in standard form.
. .
Then I would use my favorite method for solving a system of equations:
. . elimination, substitution, augmented matrix, Cramer's Rule, etc .
The algorithm is simple.
Step 1: Write the equations with variables on one side and constants on the other side.
Step 2: eliminate one by one the variables from the equations till you get two equations in two variables
Step 3: Find the values of two variables.
Step 4: Use these values to find the values of the other values.
Step : 5 You may verify the values by plugging in the values in the equations.
There is another method too that is by using matrices.
