Question

find the solution of the following pairs of linear equation 9x-2y=3 and 6x+5y=8 by elimination method​

Answer 1

Answer:

Final Answer: x=0.60, y=1.2

Step-by-step explanation:

Equation a) 9x-2y=3

Equation b) 6x+5y=8

Step 1) Choose a variable to make the same, for example the y value:

a) (x5) 45x-10y=15

b) (x2) 12x+10y=19

Step 2) Add equations together to get rid of the y:

 45x-10y=15

+ 12x+10y=19

=57x=34

x=34/57 = 0.5964.. = 0.60

Step 3) Substitute x into equation a to find y:

Equation a) 9x-2y=3

                =9(0.6)-2y=3

                =5.4-2y=3

                =2.4=2y

                =y=1.2

Final Answer: x=0.60, y=1.2
