Answer 1

ho kuch rho ndm kuch ho name

Answer 2

Given :

• The given equation is 5x+3y-7z=0

To Find :

• The remaining values comes from this equation=?

Solution :

• x=4

• y=-5

• z=8

Substituting the values of x, y, z in given equation :

$\implies \sf \: 5x + 3y - 7z = 0$

$\implies \sf \: 5(4) +3 ( - 5) - 7(8) = 0$

$\implies \sf \: 20 - 15 - 56$

$\implies \sf \: 5 - 56$

$\implies \boxed{ \bf{ - 51}}$

The remainder of this equation is -51 .
