1. 4x + 5y = 19 या समीकरणाचा आलेख काढण्यासाठी x = 1 असताना y ची किंमत -
असेल.

Answer 1

Answer:

y=3

Explanation:

4x+5y=19

..4(1)+5y=19

5y=19-4

y=15/5

y=3

Answer 2

Given :  4x + 5y = 19 या समीकरणाचा आलेख काढण्यासाठी x = 1 असताना

Equation 4x + 5y = 19 and x = 1

To Find : y   किंमत -

Value of y

A)4

B3

C)2

D)-3

Solution:

4x + 5y = 19

x = 1

=> 4(1) + 5y = 19

=> 4 + 5y = 19

Subtract 4 from both sides

=> 4  - 4 + 5y = 19 - 4

=> 5y = 15

Divide by 5 on both sides

=> 5y/5 = 15/5

=> y = 3

Value of y is 3 if x = 1

x = 1 असताना y ची किंमत  3 असेल.
