Question

Two lines, A and B, are represented by the equations given below:

Line A: 2x + 2y = 8
Line B: x + y = 4

Which statement is true about the solution to the set of equations?

Answer 1

Since 2B=A....

2(x+y=4)=2x+2y=8 which is the same as A

Both equations describe the same line, therefore, the solution set is all real numbers.
