Answer 2

It looks like you've provided a list of equations, and it seems like you want to solve for the value of x in each of them. Let's go through each equation and find the solution:

1. 6x - 28 - x = 0

Combine like terms:

5x - 28 = 0

Now, add 28 to both sides:

5x = 28

Finally, divide both sides by 5 to isolate x:

x = 28 / 5 x = 5.6

2. 9x - 26 = 30 - 5

Combine like terms:

9x - 26 = 25

Now, add 26 to both sides:

9x = 25 + 26 9x = 51

Finally, divide both sides by 9 to isolate x:

x = 51 / 9 x = 17/3 or approximately 5.67

3. 7 - 3x = 6x - 56

First, let's isolate the x terms on one side by adding 3x to both sides:

7 + 56 = 6x + 3x

63 = 9x

Now, divide both sides by 9 to isolate x:

x = 63 / 9 x = 7

4. 0.9x = 7.4 - 0.4x + 4.3

Combine like terms on the right side:

0.9x + 0.4x = 7.4 + 4.3

1.3x = 11.7

Now, divide both sides by 1.3 to isolate x:

x = 11.7 / 1.3 x = 9

5. 5.8 - 1.6x = 0.3x - 1.8

First, let's move the terms involving x to one side by adding 1.6x and 1.8x to both sides:

5.8 + 1.8 = 0.3x + 1.6x

7.6 = 1.9x

Now, divide both sides by 1.9 to isolate x:

x = 7.6 / 1.9 x = 4

6. (3/8)x + 19 = (7/12)x + 24

First, let's clear the fractions by multiplying both sides of the equation by the least common multiple (LCM) of 8 and 12, which is 24:

24[(3/8)x + 19] = 24[(7/12)x + 24]

Now, simplify each term:

(9/2)x + 456 = (7/1)x + 576

Now, isolate the x terms on one side by subtracting (7/1)x from both sides:

(9/2)x - (7/1)x + 456 = 576

Now, combine like terms:

(9/2 - 7/1)x + 456 = 576

(9/2 - 14/2)x + 456 = 576

(-5/2)x + 456 = 576

Next, subtract 456 from both sides:

(-5/2)x = 576 - 456

(-5/2)x = 120

Now, divide both sides by (-5/2) to isolate x:

x = (120) / (-5/2)

To divide by a fraction, you can multiply by its reciprocal:

x = (120) * (-2/5)

x = -48

So, the solutions to the equations are:

1. x = 5.6
2. x = 17/3 or approximately 5.67
3. x = 7
4. x = 9
5. x = 4
6. x = -48
