Question

fie numerele a b c daca a=9×7-2×4-5×10 b =98-(7×7+3×7+5×3 c=(13+7×4)-39 calculeza 2a +3c-b b+4a-2c (a+c)×9-b

Answer 1

a=63-8-50=5
b=98-(49+21+15)=13
c=41-39=2
5x2+3x2-13+4x5-2x13(5+2)x9-13

Answer 2

a=63-8-50=5
b=98-(49+21+15)=98-85=13
c=(13+28)-39=41-39=2
2a+3c-b=10+6-13=3
b+4a-2c=13+20-4=29
(a+c)*9-b=7*9-13=63-13=50
