MODEL: 720:a+450:3=240
720:a+150=240
720:a=240-150
720:a=90
a=720:90
a=8

Answer 1

20×e-(1950+550):100=6175

20×e - 2500:100=6175

20×e - 25=6175

20×e =6175+25

20×e=6200

e=6200:20

e=310

35×f+(800-752:4):2=551

35×f+(800-188):2=551

35×f+612:2=551

35×f+306=551

35×f=551-306

35×f=245

f=245:35

f=7

g:25+(100-1632:51)×2=286

g:25+(100-32)×2=286

g:25+68×2=286

g:25+136=286

g:25=286-136

g:25=150

g=150×25

g=3.750

244-h×5+(300-6×16):4=255

244-h×5+(300-96):4=255

244-h×5+204:4=255

244-h×5+51=255

244-h×5=255-51

244-h×5=204

h×5=244-204

h×5=40

h=40:5

h=8
