Step-by-step explanation:
Answer:
80/3 or 26 2/3
Step-by-step explanation:
-2 + y = 9 (subtract y from both sides)
-2 = 9 - y (subtract 9 from both sides)
-2 - 9 = y (multiply both sides by -1)
2 + 9 = y (simplify)
11 = y (substitute)
3x - 7 (11) = 3 (multiply)
3x - 77 = 3 (subtract 3 from both sides)
3x - 80 = 0 (subtract 3x from both sides)
-80 = -3x (multiply both sides by -1)
80 = 3x (divide both sides by 3)
80/3 = x (simplify if needed)
26 2/3 = x
Answer:
The answer to your question is the letter D.
Step-by-step explanation:
Equation
(x + 5)/(x² + 7x + 10) = (x - 4)/ (x² - 2x - 8)
Process
1.- Factor both denominators
x² + 7x + 10 = (x + 5)(x + 2)
x² - 2x - 8 = (x - 4)(x + 2)
2.- Substitute
(x + 5) / (x + 5)(x + 2) = (x - 4)/(x - 4)(x - 2)
3.- Simplify
1/(x + 2) = 1/(x - 2)
4.- Solve for x (cross multiplication)
x - 2 = x + 2
x - x = 2 + 2
0 = 4
5.- Conclusion
The solution is all real numbers except -5, -2 and 4.
There are 0 solutions because the lines are parallel and will never intersect.
