a simple case for that would just be, using an equation with an imaginary value, let's do so

when you get a "solution" or zero with an "i" or an imaginary value, is just a way to say, there's really no solution, the function never touches the x-axis
Answer:
x= -3/11
Step-by-step explanation:
Use cross multiplication:
5(x+1)= -1(6x-2)
Simplify:
5x+5= -6x+2
Subtract 5 from both sides:
5x= -6x-3
Add 6x to both sides:
11x= -3
Divide both sides by 11:
x= -3/11
Hope this helps ^-^
8: tenths
9:hundredth
7:thousandth
-3x+2 < 8
-2 -2
-3 /-3x <6/-3
x >-2
So x>-2
