-6x - 29 + 7x = 8
Combine like terms on the left
x - 29 = 8
add 29 to both sides
x = 8 + 29
x = 37

-8x + 6x - 13 = 33
Combine like terms on the left
-2x - 13 = 33
add 13 to both sides
-2x = 46
divide both sides by -2
x = -23

First equation:
-6x-29+7x=8
Combine like terms
-6+7=1
1x-29=8
Add 29 to both sides
1x=37
Divide both sides by 1
x=37

Second equation:
-8x+6x-13=33
Combine like terms
-8+6=-2
-2x-13=33
Add 13 on both sides
-2x=46
Divide both sides by -2
x=-23

A boy spent 20% of his money on books and 20% of the remainder on food.If he had $2000 left, how much money did he have at first

DENIUS [597]

Answer:

$\$3,125$

Step-by-step explanation:

Let $s$ represent the amount of money he initially started with.

After he spent 20% on books, he will have $100\%-20\%=80\%$ of his initial money left. We can represent this as $0.8s$ .

Following that, the boy spends 20% of the remainder of his money on food. Similarly, he will have $100\%-20\%=80\%$ of the remainder of money he had left after he purchased the books. Therefore, he ends up with $0.8(0.8s)=0.64s$ of his money left.
