Question

If 2x+8=16, what is the value of x+4?​

Answer 1

`\boxed{ \bold{ \huge{ \boxed{ \sf{8}}}}}`

Explanation:

First, finding the value of x

`\sf{2x + 8 = 16}`

Move 8 to right hand side and change it's sign

`\dashrightarrow{ \sf{2x = 16 - 8}}`

Subtract 8 from 16

`\dashrightarrow{ \sf{2x = 8}}`

Divide both sides by 2

`\dashrightarrow{ \sf{ (2x)/(2) = (8)/(2) }}`

Calculate

`\dashrightarrow{ \sf{x = 4}}`

Value of x is 4

Now, Substituting / Replacing the value of x in order to find x+4

`\sf{x + 4}`

plug the value of x

`\dashrightarrow{ \sf{4 + 4}}`

Add the numbers : 4 and 4

`\dashrightarrow{ \sf{8}}`

Hope I helped!
