Question

Please help me with my homework my homework question

Answer 1

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

Step-by-step 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 2

Answer:

B

28.78

A

Step-by-step 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.

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
