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:
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
