Question

(0) 15(x + 3)-3(x + 9) + 5(x + 6) = 82
(q) [7(2-y) - 5(y + 12)] - 3y + 6 = 5
(p) 9-2(x - 5) = x + 10
(r) 2(x - 1) - 6x = 10 -2(x-4)​

Answer 1

Answer:

(0) x = 2

(q) y = -3

(p) x = 3

(r) x = -10

Step-by-step explanation:

(o) 15(x + 3)-3(x + 9) + 5(x + 6) = 82

15x + 45 - 3x - 27 + 5x + 30 = 82

15x - 3x + 5x = -45 + 27 -30 + 82

17x  = 34

x =  34/17

x = 2

(q ) 7(2-y) - 5(y + 12) - 3y + 6 = 5

14 - 7y - 5y - 60 - 3y + 6 = 5

-7y - 5y -3y = -14 +60 -6 +5

-15y  =  45

y = - 45/15

y = -3

(p) 9-2(x - 5) = x + 10

9 - 2x + 10 = x + 10

-2x - x = -9

-3x = -9

x = 3

(r) 2(x - 1) - 6x = 10 -2(x-4)​

2x - 2 -6x = 10 - 2x + 8

2x -6x + 2x = 20

-2x = 20

x = -10
