To solve for x, we need to isolate x on one side of the equation. Let's do that:

-5x = -30

To get rid of the negative sign in front of x, we can divide both sides of the equation by -5:

-5x / -5 = -30 / -5

Simplifying, we get:

x = 6

So, x = 6.

To solve for x, we need to isolate x on one side of the equation. Let's do that:

12 - x/9 = 11

To eliminate the fraction, we can multiply both sides of the equation by 9:

9(12 - x/9) = 9(11)

Distributing the 9 on the left side:

108 - x = 99

To isolate x, we can subtract 108 from both sides:

108 - x - 108 = 99 - 108

Simplifying, we get:

-x = -9

Since -x is the same as -1x, we can rewrite the equation as:

-1x = -9

To solve for x, we can multiply both sides of the equation by -1:

-1(-1x) = -1(-9)

Simplifying, we get:

x = 9

So, x = 9.

To solve for x, we need to isolate x on one side of the equation. Let's do that:

-20 = -5 + 3x

To isolate 3x, we can subtract -5 from both sides of the equation:

-20 + 5 = -5 - 5 + 3x

Simplifying, we get:

-15 = 3x

To solve for x, we can divide both sides of the equation by 3:

-15/3 = 3x/3

Simplifying, we get:

-5 = x

So, x = -5.

To solve for x, we need to isolate x on one side of the equation. Let's do that:

20 = 5 - (3/8)x

To isolate (3/8)x, we can subtract 5 from both sides of the equation:

20 - 5 = 5 - 5 - (3/8)x

Simplifying, we get:

15 = -(3/8)x

To solve for x, we can multiply both sides of the equation by the reciprocal of -(3/8), which is -8/3:

15 * (-8/3) = -(3/8)x * (-8/3)

Simplifying the left side, we get:

-40 = x

So, x = -40.
