A student created a table of values to help solve the following equation: y =4x +24 and y = 2x+6...what x-value is a solution to

Yuki888 [10]

Answer:

x = negative 9 or x=-9

Step-by-step explanation:

4x+24=2x+6. We can subtract 6 from both sides to get

4x+18=2x. After that, we can switch the sides to get

2x-18=4x, so negative 18 (-18) is equivalent to 2x. We get

2x=-18, divide both sides by 2 to get x=(-9).

harina [27]

Dan started with 69 cards

Step-by-step explanation:

Let x be the initial number of cards

Then

According to "Dan bought 7 new baseball trading cards to add to his collection"

$x+7$

The next day his dog ate half of his collection.

$\frac{1}{2}(x+7)$

There are now only 38 cards left.

$\frac{1}{2} (x+7) = 38$

Multiplying both sides by 2

$x+ 7 = 38*2\\x+7 = 76$

Subtracting 7 from both sides

$x+7-7 = 76-7\\x = 69$

Hence,

Dan started with 69 cards
