Question

if 3x + 5x = -8, then x + 1 =? Can you explanation?​

Answer 1

The given question is if 3x + 5x = -8, then x + 1 =?

The data given in the question is

$3x + 5x = - 8$

then we have to find the value of

$x + 1$

let us find the value of x first, and the value of x will be obtained from the first expression.

On taking the x as a common factor, we have the expression as

$x(3 + 5) = - 8$

after adding the terms in the bracket, we get the value as

$8x = - 8$

The 8 multiplying on the left side divides the value on the right side

$x = \frac{ - 8}{8}$

Therefore, we obtained the value of x as -1.

we have to find the value of x +1.

let's substitute the value of x in the above expression we get the answer as

$x + 1 = ( - 1) + 1 = 0$

Therefore, the final answer obtained is 0

Hence, the answer to the given question is if 3x + 5x = -8, then x + 1 is 0.
