Question

e) (e - 5 x 6 + 10 x 5):5+4×8=42
​

Answer 1

Răspuns: $\purple{~\bf e =30~}$

Explicație pas cu pas:

$\bf (e - 5 \cdot 6 + 10\cdot5):5+4 \cdot8 =42$

$\bf (e - 30 + 50):5+32 =42$

$\bf (e - 30 + 50):5 =42-32$

$\bf (e + 20):5 =10~~~~\bigg|\cdot5$

$\bf (e +20)=50$

$\bf e =50-20$

$\red{\boxed{~\bf e =30~}}$
