I need help this is urgent!!

harina [27]

If you need an equation it is -3.4x=21.5

You simply divide both sides by -3.4 to get x=-6.32

if that's not right then just get on a calculator and calculate by doing what I said to divide

13 = m/4 + 7 can you show work too

lukranit [14]

The correct value of this equation is m = 24

<h3>Resolution method</h3>

This equation contains a fractional term. We note that the denominator of this equation is the term 4. Therefore, we will multiply the sides by 4:

13 = m/4 + 7

13 . 4 = 4(m/4) + 7 . 4

52 = m + 28

Now, let's isolate the variable "as negative" and after the equality - we'll be subtracting the terms:

52 = m + 28

-m = 28 - 58

-m = -24

m = 24

Therefore, the correct value of this equation will be m = 24
