Answer:
- 3x + 4 = 9x -6
- 3x + 4 = 3x + 5
- 9x + 6 = 9x + 6
Step-by-step explanation:
Let x is the variable in each type of equation
1/ an equation that has one solution:
3x + 4 = 9x -6
<=> 9x - 3x = 4+6
<=> 6x = 10
<=> x =
2/ an equation that has no solution:
3x + 4 = 3x + 5
<=> 3x - 3x = 5-4
<=> 0 = 1 impossible
3/ an equation that has infinite many solutions:
9x + 6 = 9x + 6
<=> 9x - 9x = 6 -6
<=> 0 = 0 (obvious) no matter what we put in for x
Hope it will find you well.
BTW,
KEY:
• exponents are going to be written as “^(x)”.
• if I put “huh” or “nope” or “what” (etc.) that means I don’t know how to solve it.

Answer: the first one is 9
√
5 the second one is 250√ 2 + 16 + 242i
the third one is 19√6
Step-by-step explanation:
What are two factors of -10 that add up to 9?
They are 10 and -1. 10*-1=-10
(x+10)(x-1)
