Question

How to solve this problem
x + 7 = -8

Answer 1

❄ Hi there,

let us first consider this: What should we do to get x all alone, on one side of the equation?

Since

• 7 is added to x

we should

• subtract 7 from x (and from the other side too!)

`\ \sf{x=-8-7}`

`\triangleright \ \sf{x=-15}`

That's it!

Answer 2

x + 7 = -8

(x + 7) - (7) = -8 - (7)

x = -8 - 7 = -15

The correct answer is -15
