9.4

Step-by-step explanation:

We have I 2 + 5x I = 49The I I is an inequality sign, which basically means that the answer can't be negative. We can remove these.2 + 5x = 49.Subtract the 2 from both sides.5x = 47.Divide by 5 on both sides.x = 9.4, or 9 Please answer with steps |2+5x| =4 9, №18010611, 06.10.2020 07:56

If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.

I would have to go with the first one because 2(3x-5)=1 is the same as 6x-10=1 
then all you have to do is divide 11 by 6 and the answetr should be c or in this case x=1.83 
to check your work do this 6(1.83)-10 and your answer should come to .98
all you have to do is round to 1.0

Multiplied both sides of the equation by 20

Step-by-step explanation:

In order to get rid of the fraction you need to divide the whole equation by the GCF.

1. The correct option is 2.

2. The correct option is 2.

3. The correct option is 2.

Step-by-step explanation:

Part 1.

The given equation is

-x=2-3x+6

Add 3x on both sides.

-x+3x=2-3x+6+3x

Combine like terms.

(-x+3x)=(-3x+3x)+(2+6)

2x=8

Divide both sides by 2.

\frac{2x}{2}=\frac{8}{2}

x=4

The value of x is 4. Therefore option 2 is correct.

Part 2.

The given equation is

2(3x-4) = 8 + 2x + 4

Step 1: 2(3x-4) = 8 + 2x + 4

Step 2: 6x-8 = 12 + 2x

Step 3: 6x-2x = 12 + 8

Step 4: 4x = 20

Step 5: x = 5

Student make his first mistake in step 2 and the correct step is 6x-8 = 12 + 2x. Therefore the correct option is 2.

Part 3.

The given equation is

4m-2m + 4 = -1 + 13

Step 1: 4m-2m + 4 = -1 + 13

Step 2: 4m-2m + 4 = 12

Step 3: 2m + 4 = 12

Step 4: Subtract 4 from both sides.

2m= 12-4

2m= 8

The next step is 2m= 8. Therefore the correct option is 2.
