Question

afla valoare lui x din egalitatea (x-5) : 5 + 80 = 88

Answer 1

= (x-5):5=88-80

=(x-5):5=8

=x-5=8*5

=x-5=40

=x=40+5=45

Answer 2

( x - 5 ) : 5 + 80 = 88

( x - 5 ) : 5 = 88 - 80

( x - 5 ) : 5 = 8

x - 5 = 8 × 5

x - 5 = 40

x = 40 + 5

x = 45

Verific:   ( 45 - 5 ) : 5 + 80 = 40 : 5 + 80 = 8 + 80 = 88
