Kevin wants to buy a video game for $45. He also wants to buy 2 game
sladkih [1.3K]

The inequality is 45 + 2x < 120.

x

Solution:

Given a cost of video game = $45

Number of game controllers bought = 2

Each controller costs the same amount.

Total amount to spend = $120

Let x be taken the cost of game controller.

So, 45 + 2x < 120

Subtract 45 on both sides of the inequality.

⇒ 45 + 2x – 45 < 120 – 45

⇒ 45 – 45 + 2x  < 120 – 45

⇒ 2x  < 75

Divide by 2 on both sides of the inequality, we get

⇒ x

Hence, Kevin spend $\frac{75}{2} for each game controller.

Answer:

​x=

​16

​

​333

​​  

​y=

​8

​

​283

​​  

Step-by-step explanation:

1 Solve for yy in 13+2x+y+90=18013+2x+y+90=180.

y=-2x+77y=−2x+77

2 Substitute y=-2x+77y=−2x+77 into 4x+1+8x-2y=1804x+1+8x−2y=180.

16x-153=18016x−153=180

3 Solve for xx in 16x-153=18016x−153=180.

x=\frac{333}{16}x=

​16

​

​333

​​  

4 Substitute x=\frac{333}{16}x=

​16

​

​333

​​  into y=-2x+77y=−2x+77.

y=\frac{283}{8}y=

​8

​

​283

​​  

5 Therefore,

\begin{aligned}&x=\frac{333}{16}\\&y=\frac{283}{8}\end{aligned}

​

​

​​  

​x=

​16

​

​333
