Question

1)10\x-4=22)6.2\3y+1=2

Answer 1

1)10/x-4=2
10=2(x-4)
10=2x-8
2x=10+8
2x=18
x= 9
2)6,2 / 3y+1=2
6,2=2(3y+1)
6,2 = 6y +2
6y = 6,2 - 2
6y=4,2
y=0,7

Answer 2

To solve the equations, I assume you meant the following:

1. 10 / x - 4 = 22
2. 6.2 / (3y + 1) = 2

Let's solve each equation step by step:

1. 10 / x - 4 = 22

To isolate the variable x, we'll first get rid of the -4 by adding it to both sides:

10 / x = 22 + 4 10 / x = 26

Next, we'll multiply both sides by x to eliminate the fraction:

10 = 26x

To solve for x, we divide both sides by 26:

10 / 26 = x 5 / 13 = x

Therefore, the solution to the first equation is x = 5/13.

2. 6.2 / (3y + 1) = 2

To isolate the variable y, we'll first multiply both sides of the equation by (3y + 1) to eliminate the denominator:

6.2 = 2(3y + 1) 6.2 = 6y + 2

Next, we'll subtract 2 from both sides:

6.2 - 2 = 6y 4.2 = 6y

To solve for y, we divide both sides by 6:

4.2 / 6 = y 0.7 = y

Therefore, the solution to the second equation is y = 0.7.

In summary:

1. x = 5/13
2. y = 0.7
