Answer:
x=+5
Step-by-step explanation:
3(x+2)-2x-7=-(-5x-1)-2(x+6)
We move all terms to the left:
3(x+2)-2x-7-(-(-5x-1)-2(x+6))=0
We add all the numbers together, and all the variables
-2x+3(x+2)-(-(-5x-1)-2(x+6))-7=0
We multiply parentheses
-2x+3x-(-(-5x-1)-2(x+6))+6-7=0
We calculate terms in parentheses: -(-(-5x-1)-2(x+6)), so:
-(-5x-1)-2(x+6)
We multiply parentheses
-(-5x-1)-2x-12
We get rid of parentheses
5x-2x+1-12
We add all the numbers together, and all the variables
3x-11
Back to the equation:
-(3x-11)
We add all the numbers together, and all the variables
x-(3x-11)-1=0
We get rid of parentheses
x-3x+11-1=0
We add all the numbers together, and all the variables
-2x+10=0
We move all terms containing x to the left, all other terms to the right
-2x=-10
x=-10/-2
x=+5
I’m not sure but I think 8
Yes, is 218cm.
15+16+20+57+20+16+15+16+(57-15-15)+16=218cm
Answer:
19 for each one
Step-by-step explanation:
Divide 57 by 3
The answer to this question is D: 2. To solve this, you must work backwards, and what's the oppsite of addition? Subtraction! Take 2.34, your final answer, and subtract .34 from it, and you end up with 2! I hope this helped! Could I possible get brainliest?
