I have no idea how to do this please help….

Answer 1

Answer:

Cost of one bush = 23

Cost of one tree = 47

Step-by-step explanation:

Let cost of bushes be x per piece

Let cost of trees be y per piece

First order : 13x + 4 y = 487    ----(1)

Second order : 6x + 2y = 232 -----(2)

multiply (1) by 6   => 78x + 24y = 2922 ----(3)

multiply (2) by 13 => 78x + 26y = 3016 -----(4)

(3) - (4) ==> -2y = -94

                    y = 47

Substitute y = 47 in (1) ==> 13x + 4(47) =487

                                         13x = 487 - 188

                                           13x = 299

                                             x = 23
