I’m supposed to solve this by eliminating the x variable

Mathematics
1 answer:
liberstina [14]3 years ago

Answer:

the answer is (-4, 5)

Step-by-step explanation:

Let's use elimination by addition / subtraction:

-6x - 2y =  14

6x + 7y = 11

-------------------

        5y   = 25, so y = 5.

Substituting 5 for y in the 2nd equation, we get:

6x + 7(5) = 11, or:

6x + 35 = 11, or

6x = -24, or x = -4.

Thus, the answer is (-4, 5).  Please double check to ensure you have copied down both system of equations and answer correctly.

Check:  Is (-4, 5) a solution to this system?

Subst. -4 for x and 5 for y in the first equation:

            -3(-4) - (5) = 7

               12 - 5 = 7  YES

(10pts) Ivan bought three games and paid $65 for all three. The second game was 50% more expensive than the first one. The price
lutik1710 [3]

We are required to find the price of the first game

The price of the first game is $20

Given:

let

price of the first game = x

price of the second game = x + 50% of x

= x + 0.5x

= 1.5x

Price of the third game = 50% of 1.5x

= 0.5 × 1.5x

= 0.75x

Total cost of game = $65

<em>Total cost of game = price of the first game + price of the second game + Price of the third game</em>

65 = x + 1.5x + 0.75x

65 = 3.25x

divide both sides by 3.25

x = 65 ÷ 3.25

x = 20

Therefore, the price of the first game is $20
