2 x(3 + 2 x x ) = 54

2(3 + 2x)
6+4x=54

4x = 54-6
4x = 48
4x/4 = 48/4
x = 12

The answer for x – y = 2 and x + y = –3 using elimination steps
jasenka [17]

The solution for the given system of equations (x,y) is (-1/2, -5/2).

<u>Step-by-step explanation:</u>

The given system of equations are :

x - y = 2  ------(1)

x + y = -3  -------(2)

To solve the system of equations, you can use elimination method.

In this method, the first step is followed by adding both the equations.

    x - y = 2  

(+) <u>x + y = -3 </u>

   <u>2x     = -1  </u>

⇒ 2x = -1

divide by 2 on both side, to get x value.

⇒ x = -1/2

The value of x is -1/2

The second step is to substitute x = -1/2 in any of the two equations.

Put x = -1/2 in equation (1),

⇒ -1/2 -y = 2

Cross multiply the denominator 2 on both sides,

⇒ -1-2y =4

Add 1 on both sides,

⇒ -2y = 4 + 1

⇒ -2y = 5

Divide by -2 on both sides,

⇒ y = -5/2

The value of y is -5/2

The solution to the system of equations is be given by (x,y).

Therefore, the solution is (-1/2, -5/2).

PLZ HELP ASAP! WILL MARK BRAINLIEST! HURRYYY! Mary went to the circus. During the dog show, she counted 54 legs between the dogs
babymother [125]

Answer:

Three ppl, Twelve dogs

Step-by-step explanation

x=hoomans

y=doggos

x+y=15

2x+4y=54

x=15-y

2(15-y)+4y=54

30-2y+4y=54

2y=24

y=12

so that means there are 12 doggos

and since x=15-y, which is 15-12, which is 3,

there are three hoomans
