Question

3x+5y=12;7x-6y=4 solve this equation in substitution method​

Answer 1

Answer:

X = 92/53 , Y = 72/53

Step-by-step explanation:

Given -

3X + 5Y = 12 -> equation (1)

7X - 6Y = 4 -> equation (2)

From equation (1),

X = 12 - 5Y/3

by putting this value of X in equation (2), we get :

7(12-5Y/3) - 6Y = 4

solving the above equation for Y, we get Y = 72/53

by putting this value of Y in equation (1), we get:

3X + 5(72/53) = 12

solving the above equation for X , we get X = 92/53
