Question

WHAT IS 10x+55 = 100​

Answer 1

• Subtract 55 from both sides.

10x=100-55

• Simplify 100-55 to 45.

10x=45

• Divide both sides by 10.

`x = (45)/(10)`

• Simplify

`x = (9)/(2)`

Answer 2

`x=\cfrac{9}{2}\: or\: x=4.5`

Explanation:

`10x+55 = 100`

`10x+55-55=100-55`

`10x=45`

`\cfrac{10x}{10}=\cfrac{45}{10}`

`x=\cfrac{9}{2}`
