Answer 1

1200 : a = 80
1200 : 80 = a
1200 : 80 = 15
a = 15
spr. 1200 : 15 = 80

40 x a = 7200
7200 : 40 = a
7200 : 40 = 180
a = 180
spr. 40 x 180 = 7200

a x 25 = 4500
4500 : 25 = a
4500 : 25 = 180
a = 180
spr. 25 x 180 = 4500

514 + a = 1000
1000 - 514 = a
1000 - 514 = 486
a = 486
spr. 514 + 486 = 1000

a : 5 = 15
5 x 15 = a
5 x 15 = 75
a=75
spr. 75: 5= 15

a+ 620 = 805
805-620=a
805-620=185
a=185
spr. 185+ 620=805

a - 15 = 0
0 + 15 = a
0+ 15 = 15
a=15
spr 15-15=0

1000 - a = 512
1000 - 512 = a
1000 - 512 =488
a=488
spr. 1000-488=512
