Answer:
18
Step-by-step explanation:
x+x+17+6=49
2x=36
x=18
s1=18
s2=35
s3=6
Part A: first multiply 2 by x and -3, then combine the like terms, after that add 6 from both sides, then subtract 6x from both side, the answer is -5.
4x + 2(x-3) = 4x + 2x - 11
4x +2x -6 = 4x + 2x - 11
6x -6 = 6x - 11
6x = 6x -11 +6
6x = 6x -5
6x-6x= -5
0 = -5
part B) add the like terms
You can form 2 and then you have the odd one out.
