0.08(y-5) + 0.14y = 0.02-0.07 (30)



-4(t-2)+9t=7t-1



7(3n-2)=(9n+2)+3

Answer 1

0.08(y - 5) + 0.14y = 0.02 - 0.07(30)
8(y - 5) + 14y = 2 - 7(30)
8y - 40 + 14y = 2 - 210
22y - 40 = -208
22y = -168
y = -168/22
y = -84/11

-4(t - 2) + 9t = 7t - 1
-4t + 8 + 9t = 7t - 1
8 + 5t = 7t - 1
9 = 2t
t = 9/2

7(3n - 2) = (9n + 2) + 3
21n - 14 = 9n + 5
12n = 19
n = 19/12

Answer 2

0.08(y - 5) + 0.14y = 0.02 - (0.07)(30)

0.08y - 0,4 + 0.14y = 0.02 - 2.1

.22y - 0.4 = - 2.08

.22y - 0.4 + 0.4 = - 2.08 + 0.4

.22y = - 1.68

.22y/.22 = - 1.68 / .22

y = - 1.68/.22

y = - 7.63636363636

- - - - - - - - - - -

- 4(t - 2) + 9t = 7t - 1

- 4t + 8 + 9t = 7t - 1

5t + 8 = 7t - 1

5t + 8 - 5t = 7t - 1 - 5t

8 = 2t - 1

8 + 1 = 2t - 1 + 1

9 = 2t

9/2 = 2t/2

9/2 = t

7(3n - 2) = (9n + 2) + 3

21n - 14 = 9n + 2 + 3

21n - 14 = 9n + 5

21n - 14 - 9n - 9n + 5 - 9n

12n - 14 = 5

12n - 14 + 14 = 5 + 14

12n = 19

12n/12 = 19/12

n = 19/12
