Answer:

x=14/5

Step-by-step explanation:

Group like terms

2x+8x+7=35

Add similar elements: 2x+8x=10x

10x+7=35

Subtract 7 from both sides:

10x+7−7=35−7

Simplify

10x=28

Divide both sides by 10

10x/10 =28/10

Simplify:

x=14/5

Shelly has a certain amount of money. If she spent 12 dollars of it. She has 1/5 left of it. How much did shelly have originally

Lena [83]

Answer:

$14.40

Step-by-step explanation:

She spent 12 dollars and has 1/5 left.

This means $12 is 4/5 of her original money.

$12=4/5 of the original money

$12+ $[12•(4/5)]=4/5+ (1/5)

$12+$[2.4]=5/5

$14.4=5/5 of the original money

She originally had $14.40
