Ответ:
C) (2,6/B)
this one is correct.
Step-by-step explanation:
here's the solution: -
the given equations are ,
=》3x +By =12
=》2x + By =10
if we subtract equation 2 from equation 1 , we get
=》3x + By - 2x - By = 12 - 2
=》x = 2
now, plugging the value of x as 2 in equation 1 we get :
=》(3 × 2) + By = 12
=》6 + By = 12
=》By = 6
=》y = 6 / B
Ответ:
using elimination method to eliminate by subtracting equation two from equation one.
3x - 2x = 12-10
x = 2
substitute x= 2 into equation one
3(2) + By = 12
6 + By = 12
By = 12 - 6
By= 6
y = 6/b
answer is option C
(2, 6/B)
