Question

(y+4)-(y-1)=6y (13х-15)-(9+6х)=-3х

Answer 1

1)у+4-у+1=6у

5=6у

у=5/6

2)13х-15-9-6х=-3х

7х-24=-3х

10х=24

х=2,4

Answer 2

(y+4)-(y-1)=6y

y+4-y+1=6y

6y=5

y=5\6

 

(13х-15)-(9+6х)=-3х

13x-15-9-6x=-3x

13x-6x+3x=15+9

10x=24

x=2.4

Answer 3

Let's solve each equation step by step:

1. (y+4)-(y-1)=6y

First, we need to simplify the left side of the equation by removing the parentheses:

y + 4 - y + 1 = 6y

The y and -y terms cancel out, and we're left with:

5 = 6y

Now, we can solve for y by dividing both sides of the equation by 6:

y = 5/6

So the solution to this equation is y = 5/6.

2. (13x - 15) - (9 + 6x) = -3x

Again, we need to simplify the left side of the equation by removing the parentheses:

13x - 15 - 9 - 6x = -3x

Now we can combine like terms:

7x - 24 = -3x

Next, we'll add 3x to both sides to isolate the variable on one side of the equation:

7x - 24 + 3x = 0

Simplifying, we get:

10x - 24 = 0

Adding 24 to both sides, we get:

10x = 24

Finally, we can solve for x by dividing both sides by 10:

x = 2.4

So the solution to this equation is x = 2.4.
