Question

explain - substitution method​

Answer 1

Step-by-step explanation:

The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other

Answer 2

Substitution method:- It is a method of solving equations.yaar mai aapko hindi me bata deta hu ok .

yaar dekho iss type ke question me 2 equation diye hote hai aur variable ka value puchta hai to hum log kya karte hai ke kisi ek equation se kisi ek variable ki values ko dusare equation me rakhte hai . aur phir issi tarah dono variable ki values hame mil jati hai .

For example===>

Two equation are give

i.e x+y=2--------(1)

2x+y=4-----(2)

from equ-----(1)

we get, x=2-y

put above value in equ-----(2)

so, 2(2-y)+y= 4

$\implies$4-2y=4

$\implies$ 2y=4-4

$\implies$ 2y=0

$\implies$ y= 0

Now, put y=0 in equ----- (1)

$\implies$x+0=2

$\implies$x=2

i hope aapko samaj aaya

AGAR SAMAJ AA GAYA HO TO BRAINILIST KAR DENA
