Question

cine imi poate rezolva problema
triplul jumatatii lui,micsorat cu 28 este 755

Answer 1

[(a÷2)×3]-28=755
(a÷2)×3=755+28(783)
a÷2=783:3(261)
a=2×261
a=522

Answer 2

Salut,

[( x ÷ 2 ) × 3 ] - 28 = 755
( 755 + 28 ) ÷ 3 × 2 =
( 783 ÷ 3 ) × 2 =
261 × 2 =
522

$x => 522$

Proba:

[( 522 ÷ 2 ) × 3 ] - 28 =
( 261 × 3 ) - 28 =
783 - 28 =
755 ✔
