Question

Pick out the solution from the values given in the bracket next to the equation. Show that the other values do not satisfy the equation.

(iv) $n+4=2\left(-2,0,2,4\right)$

Answer 1

Given: $n+4=2\left(-2,0,2,4\right)$ is the equation.

Now,

For, $n=-2$

LHS $=-2+4=2=$RHS

Here, LHS$=$RHS. Therefore, $n=-2$ is a solution.

For, $n=0$

LHS $=0+4=4\ne 2=$RHS

Here LHS$\ne$RHS. Therefore $n=0$ is not a solution.

For, $n=2$

LHS $=2+4=6\ne 2=$RHS

Here, LHS$\ne$RHS, Therefore, $n=2$ is not a solution.

For, $n=4$

LHS $=4+4=8\ne 2=$RHS

Here, LHS$\ne$RHS. Therefore, is not a solution.

Hence, $n=-2$ is the solution to the given equation
