–9

Answer 1

1) x is 6 because you need to divide 30 by 5 so you can get x by itself

Answer 2

2) (9 - 8)²(24 - 63) = 1²(- 39) = - 39...The answer is -39

Answer 3

3) okay, subtract 9 from both sides

-2x = 15-9

-2x = 6

x = -3

Answer 4

1;x=-6 3;x=12 4; x=-4 5;9

Answer 5

4) -2x-15=6x+9

-8x=24

-x=3

x=-3

Answer 6

-4(2x-1)= -6(x+2)-2

-4(2x)-4(-1)= -6(x)-6(2)-2

-8x+4=-6x-12-2

-8x+4=-6x-14

-8x=-6x-18

8x=6x+18

2x=18

x=9

Answer 7

2;= (9 - 8)²(24 - 63)
= 1²(- 39)
= - 39

Answer: - 39
