Answer:

(B) Subtract 3x from both sides of the equation, and then divide both sides by 2.

Can't read the second question fully.

(A) 0.53

Explanation:

Number 1:

If we have the equation
3x + 2 = 5x, our first goal is to get rid of the x term on one side.

To do this we can subtract 3x from both sides. This leaves our equation to
2=2x. To find x, we want to divide both sides by 2 since 2x divided by 2 is just x. Our goal is to isolate x. This leaves
x=1.

I couldn't read Number 2 fully - I'm sorry :c

Number 3:

Given the equation
3(x+0.2)=2.2, we want to isolate x on one side.

To do this, we first apply the distributive property to the left side.


3x + 0.6 = 2.2

Now subtract 0.6 from both sides:


3x=1.6

And divide both sides by 3.


x=0.5\overline{3}

This rounds to 0.53.

Hope this helped!

Answer:

B

28.78

A

Explanation:

Equation

3x + 2 = 5x

The first step is to subtract 3x from both sides.

3x - 3x + 2 = 5x - 3x

2 = 2x

The next step is to divide by two. That's the 2 in front of the two x.

2/2 = 2x/2

1 = x

So the answer must be B

The others are just not done in the right order and give wrong answers.

==================

Sorry didn't see the other two.

problem 2

4 Tires (4*122.57) 488.28 (Subtract)

Installation 65.00

Monique

Total Cost 585.34

Tires (4*136.71) 546.84 (Subtract)

Installation 38.50

Difference 26.50 (Subtract from 65)

Problem 3

3(x + 0.2) = 2.2

3x + 0.6 = 2.2

3x + 0.6 - 0.6 = 2.2 - 0.6

3x = 1.6

x = 1.6/3

x = 0.53
