Question

5. Solve each of the following for x , where x is an integer. (a) x+3=-x-17

Answer 1

Equations

To solve the equation, isolate x.

x + 3 = -x - 17

x + x = -17 - 3

2x = -20

x = -10

∴ x = -10

Answer 2

x = - 10

Explanation:

x + 3 = - x - 17 ( add x to both sides )

2x + 3 = - 17 ( subtract 3 from both sides )

2x = - 20 ( divide both sides by 2 )

x = - 10
