What is the solution to the system of equations? 3x-6y=-12 x-2y=-8 (a) use the substitution method to justify that the given system of equations has no solution. show all work! (b) what do you know about the two lines in this system of equations?

(a) Given system:

From (2), , substitute this value of x in (1), we get

Hence, the given system of equations has no solution.

(b) If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.

step-by-step explanation: where's the phrase?

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
