Question

a) ( 6400 + 2600) - 3x = 1200
b( 4x - [( 8000 - 3567 ) - ( 2031 - 1598 ) ] = 400
c) 2448 : [( 119 - ( x-6)]= 24

Answer 1

a,(6400+2600)-3x=1200

9000-3x=1200

3x=9000-1200

3x=7800

x=7800:3

x=2600

b,(4x-[(8000-3567)-(2031-1598)]=400

(4x-[4433-433]=400

4x-4000=400

4x=400+4000

4x=4400

x=4400:4

x=1100

C;2448:[(119-(x-6)]=24

119-(x-6)=2448:24

119-(x-6)=102

x-6=119-102

x-6=17

x=17+6

x=23

Answer 2

a. (6400+2600) -3x=1200

=> 9000-3x=1200

=> 3x=9000-1200

=> 3x=7800

=> x=7800:3

=> x=2600

b. {4x-[(8000-3567)-(2031-1598)]}=400

=> { 4x-(4433-433)}=400

=> 4x-4000=400

=> 4x=400+4000

=> 4x=4400

=> x=4400:4

=> x=1100

c. 2448:[(119-(x-6)]=24

=> 119-(x-6)=2448:24

=> 119-(x-6)=102

=> x-6=119-102

=> x-6=17

=> x=17+6

=> x=23

Answer 3

a :2600

b:1100

c:23

Answer 4
