Please help me with my homework my homework question
Paladinen [302]

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.

<em>I couldn't read Number 2 fully - I'm sorry :c</em>

<em></em>

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!

Check the consistency of 2x-3y=7 and x-2y+1=0
Furkat [3]

Answer:

x = 17, y = 9

or as an ordered pair, (17, 9).

The equations are consistent.

Step-by-step explanation:

2x - 3y = 7

x - 2y  = -1        Multiply this equation by -2:

-2x + 4y = 2     Add this to the first equation:

y = 9.

Plug y = 9 into the second equation:

x - 2*9 = -1

x = -1 + 18 = 17.
