Simplify the following expressions
1. 2(3 + 4x) - 9x + 1 =
2. 6(4 - x) - 2(5 - 2x) =
3. 4(3x + 5) + 7x - 5(2x - 1) =
4. 3(10 - 3x) + 2(4x + 1) - 8x + 15 =
5. 10 - 4x - 2(6 - x) + 2(3x + 5) - 3(x - 2) =
6. 5x + 12 + 4(x + 1) - 3(7 - 3x) - 2(x + 8) =
7. 3(3x + 7) - 7(x - 3) - 12x - 2(x - 1) + 4 =
8. 2(x - 6) + 3(8 - 5x) - 7x + 4(x + 2) + 5 =

the first sum answer is
2(3+4x)+9x+1=0
6+8x-9x+1=0
-x+8=0
8=x
x=8
the second sum answer is
6(4-x)-2(5-2x)=0
24-6x-10-4x=0
-10x+14=0
-10x=-14
x=-14/10
x=-7/5
there are so many questions but I can't do it
