Question

Again, it looks easy but I cannot thinkkkk

Answer 1

The correct answer option is D.
`x=(4y+2)/(5)`.

Explanation:

We are given the two models that represent the following equation:

`5x+1=4y+3`

We are to determine whether which of the given equations in the answer options can be used to find the value of x.

To find the equation, we will make
`x` the subject in
`5x+1=4y+3`.

`5x=4y+3-1`

`5x=4y+2`

`x = \frac { 4 y + 2 } { 5 }`

Therefore, the correct answer option is D.

Answer 2

For this case we have the following equation:

`5x + 1 = 4y + 3`

We must indicate an equivalent equation that allows to obtain the value of the variabale "x"

To do this, we clear x from the given equation:

We subtract 1 from both sides of the equation:

`5x = 4y + 3-1\\5x = 4y + 2`

We divide between 5 on both sides of the equation:

`x = \frac {4y + 2} {5}`

ANswer:

Option D
