Answer:
x = -119/3 = -39 2/3
Step-by-step explanation:
(128 +7x- 12) = (4x - 3)
Combine like terms
(116 +7x) = (4x - 3)
Subtract 4x from each side
116 +7x-4x=4x-4x-3
116 +3x = -3
Subtract 116 from each side
116-116 +3x = -3-116
3x = -119
Divide each side by 3
3x/3 = -119/3
x = -119/3
x = -39 2/3
Answer:
C) 4/(x+y)²
Step-by-step explanation:
start by expanding so it is written as 2÷(x+y)/(x+y)÷2.
Then rearrange so that it is 2×2/(x+y)×(x+y) or 4/(x+y)²
Answer: 1/18 or .056
