Question

A number is doubled and then increased by seven. The result is ninety three. What is the origonal number

Answer 1

Subtract 7 from both sides
2 . x = 86 Divide both sides by 2
X = 43

Answer 2

`\hbox {Let x - to be your number.}`


`2x+7=93` ⇒
`2x=93-7` ⇒
`2x=86`


`x= (86)/(2)` ⇒
`\boxed {x=43}`
