Answer:

u = -1

Step-by-step explanation:

[tex]2u + 7 = 5[/tex]

[tex]2u + 7 - 7 = 5 - 7[/tex]

[tex]2u = 5 - 7[/tex]

[tex] - (7 - 5) = - 2[/tex]

[tex]2u = - 2[/tex]

[tex]u = - 2 \div 2 = - 1[/tex]

[tex]\boxed{\green{u = - 1}}[/tex]

  • Solve ⇨ 2u + 7 = 5

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

[tex] \sf \: 2u+7 = 5[/tex]

Subtract 7 from both sides.

[tex] \sf \: 2u=5-7 [/tex]

Subtract 7 from 5 to get -2.

[tex] \sf \: 2u=-2 [/tex]

Divide both sides by 2.

[tex] \sf \: u=\frac{-2}{2} \\ [/tex]

Divide -2 by 2 to get -1.

[tex] \boxed{ \boxed{ \bf \: u=-1 }}[/tex]
