Question

What is the value of x 3+ x = -5

Answer 1

Answer is -8
Step by step

To solve for “x” we need to first isolate x on one side of the = sign.

3 + x = - 5
Subtract 3 from both sides.
3 - 3 + x = - 5 + ( -3)
(the 3 and -3 cancel each other)

x = -5 -3

X .= - 8

That’s your answer!

Answer 2

Hello there! Given the equation 3 + x = -5, x = -8.

When adding a negative and a positive, it is the same principle of subtracting the numbers and taking the sign of the larger number. To find what x represents, we use inverse operations which means to subtract -5 - 3.

Given the expression:

-5 - 3 = -8

One thing to consider when subtracting a negative and positive is that it is the same thing as doing the inverse of subtracting; it means to add the numbers and possess the sign of the larger number.

Therefore, to find what x equals, we would add 5 + 3 which gives us 8. Since 5 is greater than 3, the negative sign is kept for the answer. Because of this, -5 - 3 = -8.

x = -8
