Question

Use the substitution method to determine whether the system of equations has one solution, no solution, or infinitely many solutions.
2x - y = 10
x = 1/2y + 5
Select one:
a. The system has infinitely many solutions; the two equations are the same line.
b. It is impossible to determine from the information given.
c. The system has one solution; the two equations intersect at one point.
d. The system has no solution; the lines are parallel.

Answer 1

It is di think

Answer 2

thanks

Answer 3

2(1/2y+5)-y=10
y+10-y=10
10=10
D is correct
