10 = 13y + 12x
12x + 13y = 19
Choose the correct answer below.
A.
The system has no solution.
B.
The system has one solution.
C.
The system has infinitely many solutions.
B. The system has one solution.
What advantages does the method of substitution have over graphing for solving systems of equations?
Question content area bottom
Part 1
Choose the correct answer below.
A.
Graphing cannot be used to solve dependent or inconsistent systems due to the nature of the lines involved. Substitution can solve these.
B.
When using the graphing method, if either coordinate in the solution is a fraction, guessing the values may be required. Substitution requires no guessing.
C.
It is easier to solve application problems with substitution than with graphing.
D.
Since both methods are capable of solving a system, substitution has no advantages over graphing.
