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? It is (8, 4). It is (4, 8). There is no solution. There are infinitely many solutions.
Please Help!!!! Will Give 100 points to the Best answer.

Answer 1

Line A: 2x + 2y = 8

Line B: x + y = 4

Multiply line B by 2

Line B: 2x +2y = 8

Now you have:

Line A: 2x + 2y = 8

Line B: 2x +2y = 8

--------------------------------subtract

0 = 0

Answer

There are infinitely many solutions.
