Somebody please help me with this !!!

Step-by-step explanation:

Case 1 :

3x + 2y = 6 \\ 4x + y = 2 \\ 3x = 6 - 2y \\ x =  \frac{6 - 2y}{3}  = \\ x = 2 -  \frac{2y}{3}  \\ 4(2 -  \frac{2y}{3} ) + y = 2 \\ 8 -  \frac{8y}{3}  + y = 2 \\  - 1.67y =  - 6 \\

y = 3.59 \\ x = 2 -  \frac{2y}{3}  \\x =  2 -  \frac{2 \times 3.59}{3}  \\  \\ x =  - 0.39

Case 2 :

3x + 2y = 6 \\ 4x  -  y = 2 \\ x = 2 -  \frac{2y}{3}  \\ 4(2 -  \frac{2y}{3} ) - y = 2 \\ 8 -  \frac{8y}{3}  - y = 2 \\   - 3.67y=  - 6 \\ y = 1.63

x = 2 -  \frac{2y}{3}  \\ x = 2 -  \frac{2 \times 1.63}{3}  \\ x = 2 - 1.087 \\ x = 0.913

If you select a card at random, what is the probability of getting:A number smaller than 5 (counting the ace as a 1)?
garri49 [273]

4 Aces, 4 2's, 4 3's 4 4's

= 16 cards total out of 52 cards

 so probability would be 16/52 which reduces to 4/13

Solve each system using substitution.<br><br>1. 4x= 3y-2 ; 18= 3x+y<br><br>2. 3x+2y= 23 ; 1/2x-4= y
Dovator [93]
1. 4x= 3(18-3x) - 2
4x=54-9x-2
4x+9x=52
13x=52
x=4

substitute 4 for x
4(4)=3y-2
16=3y-2
16 + 2 = 3y
y=6

So your x would be 4 and y would be 6

to check your solution substitute x and y
4(4)=3(6) - 2
16 = 16 
Therefore that's the final answer for number 1.
