How many solutions does the system have?
2 answers:
For this case we have the following system of equations:
We multiply the second equation by -3:
Thus, we observe that the second equation is equivalent to the first, if we add both we get:
The equality is fulfilled. The lines are on top of each other.
Answer:
Infinite solutions
Answer:
<h2>System of equations: 3. Infinitely many solutions.</h2><h2>Graph: 2. No solutions.</h2>
Step-by-step explanation:
If you solve the equation system using a graph, then the solution is to intersect the line.
The graph has two parallel lines (no intersection). Therefore, this system of equations has no solutions.
Algebraic solution:
21x + 6x = 42 <em>divide both sides by (-3)</em>
-7x - 2x = -14
Add both equations by sides:
7x + 2y = 14
<u>+ -7x - 2y = -14</u>
0 = 0 TRUE
Therefore the system of equations has Infinitely many solutions.
