Answer 1

Explicație pas cu pas:

a)x-397 789=268 975

x=268 975+397 789

x=666 764

v:666 764-397 789=268 975

264 769+a=912 103

a=912 103-264 769

a=647 334

v:264 769+647 334=912 103

149 589:e=99

e=149 589:99

e=1 511

v:149 589:1 511=99

i×18=5 292

i=5 292:18

i=294

v:294×18=5 292

b)c:6=13 689

c=13 689×6

c=82 134

v:82 134:6=13 689

800 005-a=548 864

a=800 005-548 864

a=251 141

v:800 005-251 141=548 864

27×m=1 593

m=1 593:27

m=59

27×59=1 593

a+176 349=402 500

a=402 500-176 349

a=226 151

v:226 151+176 349=402 500
