Answer:
1) x = -1
2) x = 37
Step-by-step explanation:
1) [tex]8 - ( - 6 - 12x) = - 10[/tex]
After opening the brackets , the sign of the numbers in the brackets would change.
[tex] = > 8 - 6 + 12x = - 10[/tex]
[tex] = > 12x + 2= - 10[/tex]
Substracting both the sides by 2 ,
[tex] = > 12x + 2 - 2 = - 10 - 2[/tex]
[tex] = > 12x = - 12[/tex]
Divding both the sides by 12 ,
[tex] = > \frac{12x}{12} = \frac{ - 12}{12} [/tex]
[tex] = > x = - 1[/tex]
2) [tex] - (7 - x) = 30[/tex]
After opening the brackets , the sign of the numbers inside the brackets would change.
[tex] = > x - 7 = 30[/tex]
Adding both the sides by 7 ,
[tex] = > x - 7 + 7 = 30 + 7[/tex]
[tex] = > x = 37[/tex]
