Question

i) 834-[(6 x 137 - 364: i): 7+ 139] : 3 = 751​

Answer 1

Răspuns: $\bf \purple{\underline{i=7}}$

Explicație pas cu pas:

Folosim metoda mersului invers pentru a rezolva exercițiul

$\bf 834-\big[\big(6\cdot 137-364:i\big):7+139\big]:3=751$

$\bf 834-751=\big[\big(6\cdot 137-364:i\big):7+139\big]:3$

$\bf 83=\big[\big(6\cdot 137-364:i\big):7+139\big]:3~~~~~\bigg|\cdot3$

$\bf 249=\big(6\cdot 137-364:i\big):7+139$

$\bf 249-139=\big(6\cdot 137-364:i\big):7$

$\bf 110=\big(6\cdot 137-364:i\big):7~~~~~~~\bigg|\cdot 7$

$\bf 770=6\cdot 137-364:i$

$\bf 770=822-364:i$

$\bf 770+364:i=822$

$\bf 364:i=822-770$

$\bf 364:i=52$

$\bf i=364:52$

$\bf \purple{\underline{i=7}}$
