Question

Aflati numarul intreg m pentru care ecuatia in necunoscuta x:
a)9+x=m,are solutia x=-24;
b)16-m=x,are solutia x=8;
c)m • x=288,are solutia x=-24;
d)x : m= |-3|,are solutia x=-333

Answer 1

a) 9+(-24)=m
9-24=m
-15=m
b) 16-m=8
-m=8-16
-m=-8|*(-1)
m=8
c)m*(-24)=288
-24m=288
m=288/(-24)
m=-12
d) |-3|=3
-333/m=3
3m=-333
m=-333/3
m=-111
