Answer:
x = -(3 y)/2
Step-by-step explanation:
Solve for x:
-2 x - 3 y + 3/(x + y) - (3 x - 3 y)/(x^2 - y^2) = 0
Simplify and substitute z = x + y.
-2 x - 3 y + 3/(x + y) - (3 x - 3 y)/(x^2 - y^2) = -y - 2 (x + y)
= -y - 2 z:
-y - 2 z = 0
Multiply both sides by -1:
y + 2 z = 0
Subtract y from both sides:
2 z = -y
Divide both sides by 2:
z = -y/2
Substitute back for z = x + y:
x + y = -y/2
Subtract y from both sides:
Answer: x = -(3 y)/2
Answer:
a = 2
Step-by-step explanation:
Given
6x - 9 = a(3x + 2)
If the coefficient of the x- term on the right side is 6 then the equation will have no solution, that is if a = 2, then
6x - 9 = 2(3x + 2) = 6x + 4 ( add 9 to both sides )
6x = 6x + 13 ( subtract 6x from both sides )
0 = 13 ← not possible
Thus equation has no solution when a = 2
Answer: $5.85
Explanation: 1.8 x 3.25 = 5.85
Answer:
If this is the question about sample space, a possible answer is 24 and 64 ways in sample space.
Step-by-step explanation:
Hopefully, this is helpful :)
The answer would be 4 because i like the number 9
