Pick out the solution from the values given in the brackets against each equation:
x-3=0
(0,3,6)
The equation , x-3=0
When,
x=0,LHS:0-3=-3RHS:0LHS≠RHS
x=3,LHS:3-3=0RHS:0LHS=RHS
x=6,LHS:6-3=3RHS:0LHS≠RHS
Hence , x=6 satisfies the equation.
n+3=7
(10,4,0)
2x=8
(10,6,4)
Pick the solution from the values given in the brackets against each equation :
x+5=11,11,5,6
