Question

Which number, when substituted for x, makes the equation 4x+8=16 true?

Answer 1

X would be 2, 4(2)+8=16.

Answer 2

`\boxed{ \bold{ \boxed{ \sf{2}}}}`

Explanation:

`\sf{4x + 8 = 16}`

Move 8 to right hand side and change its sign

⇒
`\sf{4x = 16 - 8}`

Subtract 8 from 16

⇒
`\sf{4x = 8}`

Divide both sides of the equation by 4

⇒
`\sf{ (4x)/(4) = (8)/(4) }`

Calculate

⇒
`\sf{x = 2}`
