Question

1. True or false:

The ordered pair (3, 4) is a solution for the equation:

5x + 2y = 23

2. True or false:


The ordered pair (0, 4) is a solution for the equation:

5x + 2y = 23

Answer 1

1) true

2)false

Explanation:

1) 5(3)+2(4) = 23

= 15+8=23

23=23

thus, (3,4) is solution for 5x + 2y = 23

2) 5(0)+2(4) =23

= 0+8 is not 23

thus, (0,4) is not solution for 5x + 2y = 23
