Answer: 1+5/7
Step-by-step explanation:
16-2r=3-r+6r+1
We move all terms to the left:
16-2r-(3-r+6r+1)=0
We add all the numbers together, and all the variables
-2r-(5r+4)+16=0
We get rid of parentheses
-2r-5r-4+16=0
We add all the numbers together, and all the variables
-7r+12=0
We move all terms containing r to the left, all other terms to the right
-7r=-12
r=-12/-7
r=1+5/7
Answer:
x = -8 and x = 2
Step-by-step explanation:
The given equation resolves into two:
The solution to the first can be found by subtracting 3:
x = 2
The solution to the second can be found by multiplying by -1, then subtracting 3.
x +3 = -5
x = -8
The solution set is {-8, 2}.
Answer:
You multiply 5 by 1/5 to get 1. So with 2x, you multiply by 1/(2x) to get 1. That's about all you know, since we only know that x is positive.
Step-by-step explanation:
X represents the number
4x+13=(1/2)x-8 this is the equation
4x-(1/2)x=(-8)-13 combine like terms
(3 1/2)x=-21 simplify!
(7/2)x=-21 convert 3 1/2 into a fraction
x=(-21)(2/7) multiply both sides by 2/7 in order to isolate x
The answer is X= -6
Answer:
the absolute value is 6
Step-by-step explanation:
-|6| += -6
|6|=6
|-6|=6
