Question

x+100=200-500

x+800=1000

Answer 1

x+100=200-500                                    x+800=1000

x+100=-300                                         x        =1000-800

x       =(-300)-100                                 x        =200

x       =(-300)+(-100)

x       =-400

Answer 2

x+100=200-500

x+100=-300

x=-300+100

x=-200

x+800=1000

x=1000-800

x=200

Answer 3

x+100=200-500

x+100=-300

x=-300-100

x=-400

Answer 4

x+100=200-500

x+100=-300

x=-300-100

x=-400

x+800=1000

x=1000-800

x=200

Answer 5

x + 100 = 200 - 500 

x + 100 = - 300

x = - 300 - 100

x = - 400

x - 100 = 200 - 300

x + 800 = 1000

x = 1000 - 800

x = 200
