Question

Give the answer of this equation 1+4y=-7

Answer 1

Subtract -1 from both sides,

=> 1 + 4y -1 = -7 -1
=> 4y = -8

=> y = -2,

So by solving the equation, we got the answer for y,

If you have doubt still, substitute the value in the equation,

=> 1 + 4(-2)
=> 1 -8
=> -7 = -7,

Therefore the value of y = -2, and hence verified,

Hope you understand,

Have a great day !!

Answer 2

Answer:

=> The value of y is -2.

Step-by-step explanation:

Given that:-

$1+4y = -7$

To find:- The value of the expression,

For solving this expression, we must apply the transposition method:

As we have,

=> $1+4y = -7$

First, we have to rearrange the terms:

=> $4y+1 = -7$

Now subtract both sides by $1$, we get

=> $4y+1 -1= -7-1$

Simplifying it further, we get

=> $4y= -8$

Divide both sides by $4$,

=> $y = -2$

Hence, the required solution is -2.
