Answer 1

Answer:

qu.1

$2x + 7 = 5x - 5 \\ - 3x = - 12 \\ x = 4$

Answer 2

Answer:

(1) x = 4

(2) x= -9

(3) x = 6

(4) x = 1

Step-by-step explanation:

(1) 2x+7=5x-5

5x-2x = 7+5

3x = 12

x = 12/3 = 4 ans.

(2) 14x+3 = 12x-15

14x - 12x = -15-3

2x = -18

x = -9

(3) 3x+2 = 4×5

3x = 20-2

x = 18/3

x= 6 ans

(4) 3(x+4) + 5x = 20

3x + 12 + 5x = 20

8x= 20-12

x = 8/8

x= 1
