Question

Pick out the solution from the values given in the brackets against each equation:

$n+3=7$

$(10,4,0)$

Answer 1

The equation, $n+3=7$

When , $n=10,$

$$\begin{gathered} LHS:10+3=13 \\ RHS:7 \\ LHS\ne RHS \end{gathered}$$

When , $$\begin{gathered} n=4, \\ LHS:4+3=7 \\ RHS:7 \\ LHS=RHS \end{gathered}$$

When $$\begin{gathered} n=0, \\ LHS:0+3=3 \\ RHS:7 \\ LHS\ne RHS \end{gathered}$$

Hence , $n=4$satisfies the equation.
