we can rewrite your equation as follows: $- \frac{5}{2}x - 5 = - 55$

6. Michele_Laino

now we can add +5 to both sides, so we cdan write: $\Large - \frac{5}{2}x - 5 + 5 = - 55 + 5$ please simplify

I got this: $- \frac{5}{2}x = - 50$

ok

now I divide both sides by -5 so I can write: $- \frac{5}{2}\frac{x}{{ - 5}} = \frac{{ - 50}}{{ - 5}}$

13. Michele_Laino

from which we get: $\frac{x}{2} = 10$ please multiply both sides by 2, and you will get the value of x
