Answer:
B
Step-by-step explanation:
5+2(3+2x) = x + 3(x+1)
simplify
5 + 6 + 4x = x + 3x + 3
simplify once more
11 + 4x = 4x + 3
subtract 3 from both sides
8 + 4x = 4x
divide by 4
2 + x = x
no solution, because it is saying x equals something larger than x
Answer: B) 5 + 2(3 + 2x) = x + 3(x + 1)
Step-by-step explanation:
A) 4(x + 3) + 2x = 6(x + 2)
4x + 12 + 2x = 6x + 12
6x + 12 = 6x + 12
infinitely many solutions
B) 5 + 2(3 + 2x) = x + 3(x + 1)
5 + 6 + 4x = x + 3x + 3
11 + 4x = 4x + 3
11 = 3
FALSE
No Solution
C) 5(x + 3) + x = 4(x + 3) + 3
5x + 15 + x = 4x + 12 + 3
15 + 6x = 4x + 15
15 + 2x = 15
2x = 0
x = 0
One Solution
D) 4 + 672 + x = 2(3x + 8)
676 + x = 6x + 16
660 = 5x
180 = x
