Answer: When a system of two linear equations gives an answer of 
, there are infinitely many solutions. It also means that the graph represents parallel lines, so the answer is the third choice.
Step-by-step explanation: When it comes to systems of equations in algebra, you will see three types of solutions:
1. When you get an exact value & number for x and y, the system has <u>one solution</u> and is consistent/independent.
2. When you get like in this case, the system has <u>infinitely many solutions</u> and is consistent/dependent.
3. When you get numbers that are not equal, for example, 
, you have <u>many solutions</u> and the system is inconsistent/independent.

Answer:
The equation is : x-2y+2=0.
Answer:
x=12.6
Step-by-step explanation:
5x -9 / 7
5x= -9x7
5x= -63
x= -63/5 = -12.6
x= -12.6
