Question

check (4 , -2) is the solution of equation 3x+2y=8​

Answer 1

$\huge \clubs \: Solution$

$\mathfrak\red{Substituting \: \: 4 \: and -2}$

$\purple{3(4) + 2( - 2) = 8} \\ \green{12 - 4 = 8} \\ \blue{8 = 8}$

$\pink{Hence \: proved}$

Answer 2

QUESTION :-

check (4, -2) is the solution of equation 3x + 2y = 8.

__________________________

SOLUTION :-

To check that (4, -2) is the solution of 3x + 2y = 8 or not.

(4, -2) => x = 4 & y = (-2)

3x + 2y = 8

[put the value of x & y]

=> 3(4) + 2(-2) = 8

=> 12 + (-4) = 8

=> 12 - 4 = 8

=> 8 = 8

=> LHS = RHS

So,

(4, -2) is the solution of equation 3x + 2y = 8.
