Sagot :
[tex]5x-10= -20[/tex]
- add 10 to both sides ([tex]5x= -10[/tex])
- divide each side by 5 ([tex]x= -2[/tex])
so, the answer is [tex]x= -2[/tex])))

5(-2)-10 = -20
-20 = -20
- add 10 to both sides ([tex]5x= -10[/tex])
- divide each side by 5 ([tex]x= -2[/tex])
so, the answer is [tex]x= -2[/tex])))

5(-2)-10 = -20
-20 = -20
You would do the opposite of subtracting which is adding to -10 so add 10 to -10 and add 10 to -20. The -10 now equals 0 so we can get rid of that. Now we have 5x=-10. To get rid of the 5, do the opposite of multiplying and divide 5 from 5x and divide 5 from -10. We now have x=-2! This is your final answer!
