Question

I) (4×I+5)-6×2=5 Va rog​

Answer 1

Explicație pas cu pas:

(4l +5) - 12 = 5

(4l +5) = 5+12

4l + 5 = 17

4l = 17 - 5

4l = 12

L = 12 : 4 = 3

Answer 2

Răspuns: $\purple{\bf~ \ell = 3~}$

Explicație pas cu pas:

$\bf \big (4 \cdot \ell +5\big)-6\cdot 2=5$

$\bf \big (4 \cdot \ell +5\big)-12=5$

$\bf \big (4 \cdot \ell +5\big)=5+12$

$\bf 4 \cdot \ell +5 = 17$

$\bf 4 \cdot \ell = 17-5$

$\bf 4 \cdot \ell = 12~~~\bigg|:4$

$\red{\boxed{\bf~ \ell = 3~}}$
