Question

6x+7y=4x+4y6x+7y=4x+4y6, x, plus, 7, y, equals, 4, x, plus, 4, y Complete the missing value in the solution to the equation. (((,-4),−4)

Answer 1

6,-4

Explanation:

Answer 2

The missing value in the given solution is x=6

Therefore the solution is (6,-4)

Explanation:

Given equation is
`6x+7y=4x+4y\hfill (1)`

To find the missing value in the solution to the equation :

• Let missing value in the solution be x
• Then the solution of the given equation is (x,-4)

Substitute the value of y=-4 in the given equation (1) we get

`6x+7(-4)=4x+4(-4)`

`6x-28=4x-16`

`6x-28-(4x-16)=4x-16-(4x-16)`

`6x-28-4x+16=4x-16-4x+16` ( adding the like terms )

`2x-12=0`

`2x=12`

`x=(12)/(2)`

Therefore x=6

Therefore the missing value in the given solution is x=6

Therefore the solution is (6,-4)
