Answer 1

Heya ✋

(1) 14y - 8 = 13

=> 14y = 13 + 8

=> 14y = 21

=> y = 21/14

=> y = 3/2

(2) 2x - 1 = 14 - x

=> 2x + x = 14 + 1

=> 3x = 15

=> x = 15/3

=> x = 5

(3) (3x - 4)/4 = 8

=> 3x - 4 = 8 × 4

=> 3x - 4 = 32

=> 3x = 32 + 4

=> 3x = 36

=> x = 36/3

=> x = 12

(4) x/3 - 4 = -3/4 + 3

=> x/3 - 4 = -3 + 12/3

=> x/3 - 4 = 9/3

=> x/3 - 4 = 3

=> x/3 = 3 + 4

=> x/3 = 7

=> x = 7 × 3

=> x = 21

(5) 13/4 - 6x = 4

=> - 6x = 4 - 13/4

=> - 6x = 16 - 13/4

=> - 6x = 3/4

=> x = 3/4 × (-6)

=> x = -1/8

(6) 7x + 11 = 13/4 + 2

=> 7x + 11 = 13 + 8/4

=> 7x + 11 = 21/4

=> 7x = 21/4 - 11

=> 7x = 21 - 44/4

=> 7x = -23/4

=> x = -23/4 × 7

=> x = -23/28

(7) (3y + 8)/(2 - 6y) = (-2)/5

=> 5(3y + 8) = -2(2 - 6y)

=> 15y + 40 = -4 + 12y

=> 15y - 12y = -4 - 40

=> 3y = -44

=> y = -44/3






Thanks :)))))
