Answer:
3.) 5=b
4.) x=-4
5.) n > 0
6.) x > -1
7.) v > -3
8.) a > 1
Explanation:
3.) 6(5-b)=35-7b
30-6b=35-7b
+6b on each side
30=35-b
-35 on each side
-5=-b
5=b
4.) 15+7x=2(x-5)+5
15+7x=2x-10+5
15+7x=2x-5
-2x from each side
15+5x=-5
-15 from each side
5x=-20
÷ each side by 5
x=-4
5.) 15+8n>-3(-5+3n)
15+8n>15-9n
+9n to each side
15+17n>15
-15 each side
17n>0
÷ each side by 17
n>0
6.) 4(8x+8)+5>8x+13
32x+32+5>8x+13
32x+37>8x+13
-8x each side
24x+37>13
-37 each side
24x>-24
÷ by 24
x>-1
7.) 7(5v+6)>-39+8v
35v+42>-39+8v
-8v each side
27v+42>-39
-42 each side
27v>-81
÷ by 27
v>-3
8.) -7(-5+5a)+5<7a-2
35-35a+5<7a-2
40-35a<7a-2
-7a each side
40-42a<-2
-40 each side
-42a<-42
÷ by -42
a>1
Hope this helps, i dont know how to post a pic on here so you still have to graph 5-8.
