Do you mean 3 + 4|3x + 7| ≤ - 89? There is no solution to the inequality, since it is a false statement. A positive number cannot be equal or less than a negative number. On the left side, you are dealing only with positive numbers, since the absolute value is always positive, no matter what the values of x are.

x= -1
Absolute value of -4 is 4.

no number; absolute value is always positive. The absolute value of a negative number is positive. For example absolute value of -4 is +4
x= -1
Absolute value of -4 is 4.
Absolute value of -4 is 4.
the only absolute value would be 4, as the absolute value is the space that the number is away from zero. Both positive and negative four would equal four. On the other hand, if the negative sign was outside the absolute value ( -|4| ), then the number would be negative.
Only when a and b have the same sign (or when a or b equals 0). Here are some examples: |2+4|=|2|+|4|--> |6|=|6|--> 6=6 TRUE |(-1)+(-3)|=|(-1)|+|(-3)|--> |(-4)|=1+3--> 4=4 TRUE |3+(-6)|=|3|+|(-6)|--> |(-3)|=3+6--> 3=9 FALSE
Absolute value of 4 is 4.
|x + 1| - |x + 4| = 0 ∴ |x + 1| = |x + 4| ∴ x + 1 = -x - 4 ∴ 2x = -5 ∴ x = -5/2
