Question

Solve by substitution method 3x+2y=10;4x-3y=19

Answer 1

Step-by-step explanation:

equation - 1:- 3x+2y=10

equation 2 :- 4x-3y=19

so from equation 1 ,

X= 10-2y / 3

so put this X in equation 2.

so,

4. ( (10-2y)/3) -3y = 19

40/3 - 8y/3 = 19+3y

-17/3 = 17/3 . y

so y = -1

and put this value of y in equation 1

so X = (10+2)/ 3

so X = 4
