Question

i. 4x - 7 - (x+4) = 3x + 4 - (2x - 1)
ii. 17 ( 2 - x) - 5 ( x + 12 )= 8
, ----------------------------
1-7x

Answer 1

Answer:

Step-by-step explanation:

4x-7-(x+4)=3x+4-(2x-1)

4x-7-x-4=3x+4-2x+1

3x-11=x+5

3x-x=5+11

2x=16

x=16/2

x=8

Answer 2

Answer:

SoluTion:

(1) 4x - 7 - (x + 4) = 3x + 4 - (2x - 1)

→ 4x - 7 - x - 4 = 3x + 4 - 2x + 1

→ 4x - x - 3x + 2x = 4 + 1 + 7 + 4

→ 2x = 16

→ x = 16/2

→ x = 8

(2) 17 ( 2 - x) - 5 ( x + 12 ) = 8

→ 34 - 17x - 5x - 60 = 8

→ -22x + 34 - 60 = 8

→ -22x = 8 + 26

→ x = -32/22

→ x = -16/11
