Question

How to find the solution set of an equation?

Answer 1

which equation ?

Answer 2

Lel

Answer 3

How about we try and find the solution set of:
\[7x_1-\frac{ 5 }{ 9 }x_2 = -1\]

Answer 4

let say we have an equation like 3x+4 =0
now the solution of this equation means that we have to find such value of x such that L.H.S = R.H.S
the equation is 3x+4 =0
solve for x we get
3x+4-4 =0-4
3x = -4
3x/3 = -4/3
x= -4/3 ------> required solution
to check whether this solution is right or wrong put this value of x in the given equation
3(-4/3)+4 = 0
-4+4 = 0
0 = 0
thus LHS = RHS which proves that x=-4/3 is the right solution
