Solve the equations with explaining how you got your answer

1. 25u + 74 = 23u + 92

2. -5k - 19 = 5 -13k

3. -11y + 32 = 104 - 5y

4. -15n + 16 = 86 - 29n

5. 25 + = 5 [ 5t + 1 ]

6. -24s - 53 = 39 - s

1) 25u + 74 = 23u + 92
25u - 23u = 92 - 74
2u = 18
u = 18/2 = 9

6) -24s - 53 = 39 - s
-24s + s = 39 + 53
-23s = 92
x = 92/-23 = -4

Thanks Robert: These are 1 equation , 1 unknown. Easy to learn, so here we go:
terms with variable(unknown) to one side, aka isolate unknown, can move terms from side to side by simply changing its sign:
25u + 74 = 23u + 92
25u - 23u = 92 - 74 => simplify
2u = 18 => divide by 2
u = 9

1. 25u - 23u = 92 -74
2u = 18
u = 9

2. -5k + 13k = 5 + 19
8k = 24
k = 3

3. -11y +32 = 104 - 5y
-11y + 5y = 104 - 32
-6y = 72
y = - 12

4. -15n + 16 = 86 - 29n
-15n + 29n = 86 - 16
14n = 70
n = 70/14 = 5

5. 25 + t = 5[5t +1}
25 + t = 25t + 5
20 = 24t
t = 20/24 = 5/6

6. -24s - 53 = 39 - s
-23s = 92

s = 92/23 = 4

1. 2u=18, u=9
2. 8k=24, k=3
3. 6y=--72, y=-12
4. 14n=70, n=5
5. 25=25t+5, t=30/20=3/2
6. 23s=-92, s=-4
