Question

11.3x = 15 - 2x Help me

Answer 1

Answer:  see below

Step-by-step explanation:

11.3x=15-2x

We move all terms to the left:

11.3x-(15-2x)=0

We add all the numbers together, and all the variables

11.3x-(-2x+15)=0

We get rid of parentheses

11.3x+2x-15=0

We add all the numbers together, and all the variables

13.3x-15=0

We move all terms containing x to the left, all other terms to the right

13.3x=15

x=15/13.3

x=1+1/7.8235294117647

   

Answer 2

Answer:

x= 15/13.3 = 1.1278

Step-by-step explanation:

11.3x = 15 - 2x

if we bring all the x to one side and the to the other side, we'll get :

11.3x+2x =15  ⇒13,3x = 15

To find x we divide 15 by 13.3

x = 15/13.3 = 1.1278

To control this we put 1.1278 in the formula 11.3x = 15-2x

11.3 * 1.1278 = 15 -2 * 1.1278

12.744 = 15 - 2.256

12.744 + 2.256 = 15 So it's correct
