Question

`2u+7=5`
-----

Answer 1

u = -1

Explanation:

`2u + 7 = 5`

`2u + 7 - 7 = 5 - 7`

`2u = 5 - 7`

`- (7 - 5) = - 2`

`2u = - 2`

`u = - 2 / 2 = - 1`

`\boxed{\green{u = - 1}}`

Answer 2

`\huge \boxed{\mathfrak{Question} \downarrow}`

• Solve ⇨ 2u + 7 = 5

`\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}`

`\sf \: 2u+7 = 5`

Subtract 7 from both sides.

`\sf \: 2u=5-7`

Subtract 7 from 5 to get -2.

`\sf \: 2u=-2`

Divide both sides by 2.

`\sf \: u=(-2)/(2) \\`

Divide -2 by 2 to get -1.

`\boxed{ \boxed{ \bf \: u=-1 }}`
