Pick out the solution from the values given in the brackets against each equation:
2x=8
(10,6,4)
The equation is, 2x=8
When ,
x=10,LHS:2×10=20RHS=8LHS≠RHS
When,
x=6,LHS:2×6=12RHS:8LHS≠RHS
x=4,LHS:2×4=8RHS:8LHS=RHS
Hence , x=4 satisfies the equation.
n+3=7
(10,4,0)
x-3=0
(0,3,6)
Pick the solution from the values given in the brackets against each equation :
x+5=11,11,5,6
k+1=0(-1,1,2)
