Question

determina doua numere care au ca suma 100 si diferenta 32

Answer 1

a+b=100+
a -b=  32
--------------
2a=132
a=132:2
a=66
b=34

Answer 2

a + b = 100
a - b =  32
le adunam si va rezulta

a + a + b - b = 100 + 32⇒2a = 132⇒a = 132:2 = 66⇒a = 66
a = 66  si a - b =  32⇒a - 32=b⇒66 - 32= b ⇒b = 34
b = 34
