Question

Hi can you help me yo solve this problema a+ 4 = 11

Answer 1

Given the equation :

`a+4=11`

To find a add (-4) to both sides

`\begin{gathered} a+4-4=11-4 \\ \\ a=7 \end{gathered}`

check the answer by substitution with a in the left hand side

so,

`\text{LHS}=7+4=11=\text{RHS}`

So, the answer is : a = 7
