To solve for x, we can first isolate the variable by adding 11 to both sides:
-5x - 11 + 11 = 19 + 11
-5x = 30
Next, we can divide both sides of the equation by -5 to solve for x:
(-5x)/-5 = 30/-5
x = -6
Solve for x. −5x−11=19 (1 point)

To solve for x, we can begin by moving the constant -2 to the other side of the equation by adding 2 to both sides:
x^4 - 2 + 2 = -10 + 2.
This simplifies to:
x^4 = -8.
To find the value of x, we need to take the fourth root of both sides:
∜x^4 = ∜(-8).
The fourth root of -8 can be written as -8^(1/4) or (-1) * 8^(1/4) since the fourth root of a negative number is equal to the negative of the fourth root of its absolute value.
Using a calculator, we find that the fourth root of 8 is approximately 1.68179.
Therefore, x is equal to -1 times the fourth root of 8, or x ≈ -1 * 1.68179 = -1.68179.
x^4 - 2 + 2 = -10 + 2.
This simplifies to:
x^4 = -8.
