Question

4x+6x-x=216 7y-y+3y=61,2 пж

Answer 1

4x+6x-x=216                7y-y+3y=61,2

x(4+6-1)=216                 y(7-1+3)=61,2

9x=216                         9у=61,2            

x=216:9                          у=61,2:9                  

x=24                               у=6,8

Answer 2

To solve the equations, let's start with the first one:

1. 4x + 6x - x = 216

First, combine the x terms on the left side:

4x + 6x - x = 4x + 5x = 9x

Now, the equation becomes:

9x = 216

To find the value of x, divide both sides by 9:

x = 216 / 9 x = 24

So, the solution for the first equation is x = 24.

Now, let's move on to the second equation:

2. 7y - y + 3y = 61

Combine the y terms on the left side:

7y - y + 3y = 7y + 2y = 9y

Now, the equation becomes:

9y = 61

To find the value of y, divide both sides by 9:

y = 61 / 9 y ≈ 6.78 (rounded to two decimal places)

So, the solution for the second equation is y ≈ 6.78.

To summarize:

1. x = 24
2. y ≈ 6.78
