Answer:
look below.
Explanation:
When there's a letter, it represents a variable. You need to find the value (number) of this variable. This can be done by trying to isolate (put it by itself) the variable. So now, here is how to do it:
1) -2j + 6 = 2j - 8
-2j - 2j = - 8 - 6
-4j/4 = -14/4
j = 14/4
j = 7/2
2) 4h + 6 = 2h - 8
4h - 2h = - 8 - 6
2h/2 = - 14/2
h = -7
3) 9w + 9 = 3w - 15
9w - 3w = - 15 - 9
6w/6 = -24/6
w = -4
4) 45 = -9(e + 8)
45 = -9e - 72
45 + 72 = -9e
117/-9 = e
e = -13
5) 35 = -7t
35/-7 = t
t = -5
6) 12k + 13 = 8k + 33
12k - 8k = 33 - 13
4k/4 = 20/4
k = 5
