Answer:

[tex]x=\cfrac{9}{2}\: or\: x=4.5[/tex]

Step-by-step explanation:

[tex]10x+55 = 100[/tex]

[tex]10x+55-55=100-55[/tex]

[tex]10x=45[/tex]

[tex]\cfrac{10x}{10}=\cfrac{45}{10}[/tex]

[tex]x=\cfrac{9}{2}[/tex]

HOPE IT HELPS!

  • Subtract 55 from both sides.

10x=100-55

  • Simplify 100-55 to 45.

10x=45

  • Divide both sides by 10.

[tex]x = \frac{45}{10} [/tex]

  • Simplify

[tex]x = \frac{9}{2} [/tex]
