Question

Sa se determine valorare a lui a din: 546+127-96:3+73x2-(62:a+24:2)-5x11=689

Answer 1

546 +127 -96:3+73x2-(62:a+24:2) -5 x11=689
673 - 32 + 146 - ( 62:a+12)-55=689
641+146 - (62:a+12)= 689+55
787 - (62:a+12) =744
62:a+12= 787-744
62:a+12=43
62:a=43-12
62:a=31
a=62:31
a=2

Answer 2

546+127-96:3+73x2-(62:a+24:2)-5x11=689

546+127-32+146-(62:a+12)-55=689

673-32+146-(62:a+12)-55=689

641+146-(62:a+12)-55=689

787-(62:a+12)-55=689

732-(62:a+12)=689

62:a+12=732-689

62:a+12=43

62:a=43-12

62:a=31

a=62:31

a=2
