B. 60 = 7 - 2y
40 + y = 4

(, 2 )

Step-by-step explanation:

6x = 7 - 2y → (1)

4x + y = 4 ( subtract 4x from both sides )

y = 4 - 4x → (2)

substitute y = 4 - 4x into (1)

6x = 7 - 2(4 - 4x) ← distribute and simplify

6x = 7 - 8 + 8x

6x = - 1 + 8x ( subtract 8x from both sides )

- 2x = - 1 ( divide both sides by - 2 )

x =

substitute this value into (2)

y = 4 - 4( ) = 4 - 2 = 2

solution is ( , 2 )

The given equations are ~

and

Now, let's simplify equation 2 for y

Plug the given value of y in equation 1st ;

Now, use this value of x in equation 2nd to find the value of y ;

Therefore, the required values are ~
