Question

Lines A and B are represented by the equations given below: Line A: x + 2y = 3 Line B: x + y = 3 Which statement is true about the solution to the set of equations? (1 point) There are infinitely many solutions. There are two solutions. There is one solution. There is no solution.

Answer 1

 x + 2y = 3 
 x + y = 3  -------> x=3-y (Substitute into 1st equation.)

 x + 2y = 3 
3-y+2y=3
y=0

x=3-y=3-0=3
x=3

x=3, y=0
(3,0)  
Answer: one solution.
