Assuming you typed this correctly, and how you wanted it, then the answer(s) would be x=3, or x=8. Both answers are correct. If it were multiple choice, then the answer would look something like: X=3 or 8.
If you meant 2x, then the answer would be x=8/3. This is a fraction

Answer: 0.6666666667
Step-by-step explanation: Simplifying
9t + -3t = 4
Combine like terms: 9t + -3t = 6t
6t = 4
Solving
6t = 4
Solving for variable 't'.
Move all terms containing t to the left, all other terms to the right.
Divide each side by '6'.
t = 0.6666666667
Simplifying
t = 0.6666666667
Answer:
Correct answer: (2 x - 1) (x + 2)
Step-by-step explanation:
Given:
2 x² + 3 x - 2 = ( ) · ( )
2 x² + 3 x - 2 = 2 · ( x² + (3/2) x - 1) = 2 ( x² + 2 · x · (3/4) + (3/4)² - (3/4)² - 1)
2 x² + 3 x - 2 = 2 · ( (x + (3/4))² - (9/16) - 1) = 2 · ((x + (3/4))² - (9/16) - (16/16))
2 x² + 3 x - 2 = 2 · ((x + (3/4))² - (25/16)) = 2 · ((x + (3/4))² - (5/4)²)
2 x² + 3 x - 2 = 2 · (x + (3/4) - (5/4)) · (x + (3/4) + (5/4)) =
2 · (x - (2/4)) (x + (8/4))
2 x² + 3 x - 2 = 2 · (x - (1/2)) (x + 2) = (2 x - 1) · (x + 2)
2 x² + 3 x - 2 = (2 x - 1) · (x + 2)

Answer:
.35 x + .70 (20) = .45(x+20)
50=x
Step-by-step explanation:
Let x = liters of 35% salt solution
We have 20 liters of 70%
We have a total of 20+x liters of 45%
.35 x + .70 (20) = .45(x+20)
Distribute
.35x + 14 = .45x +9
Subtract .35x from each side
14 = .10x +9
Subtract 9 from each side
5 = .10x
Divide each side by .1
5/.1 = x
50=x
