Question

X+y=3 & 2x+5y=12 by elimination method

Answer 1

Answer:

Step-by-step explanation:

solutions for given equation x = 1, y=3

Step-by-step explanation:

Given equations      _(1)

                          _ (2)

to solve equations the coefficients of any variable must be equal

2 × equation(1) ⇒    _(3)  

1 × equation(2) ⇒    _(4)  

equation(3) -equation(4) =  

                                        =  

                                        =  

                                        =

                                         =  

substitute y=2 in equation (1) ⇒  

                                                    x = 1

the solutions are x =1, y=2
