Question

what number should replace"n".4(5+n)=(4×5)+(4×3)​

Answer 1

4(5+n)=(4×5)+(4×3)

20+4n = 20+ 12

4n= 20+12-20

4n = 12

n= 12/4

n= 3

so, 3 should replace "n"

Answer 2

Answer:

$\huge\star\underbrace{\mathtt\red{⫷❥ᴀ᭄} \mathtt\green{n~ }\mathtt\blue{ §} \mathtt\purple{₩}\mathtt\orange{Σ} \mathtt\pink{R⫸}}\star\:$

Step-by-step explanation:

$\huge{\underline{\underline{Given→}}}$

• $Equation→4(5+n)=(4x5)+(4x3)$

$\huge{\underline{\underline{To\:Find→}}}$

→The value of n in the given equation.

$\huge{\underline{\underline{Answer→}}}$

$4(5 + n) = (4 \times 5) + (4 \times 3) \\ 4(5 + n) = (20) + ( 12) \\ 4(5 + n) = 32 \\ (5 + n) = \frac{32}{4} \\ (5 + n) = 8 \\ n = 8 - 5 \\ n = 3$

☞So from here, the value of n is 3 which is the required answer.
