What is the solution of the equation 11-4x=-9

To solve the equation 11-4x=-9, we can start by isolating the variable x:

11-4x=-9
First, subtract 11 from both sides:
-4x = -20

Next, divide both sides by -4:
x = -20 / -4 = 5

So the solution to the equation 11-4x=-9 is x = 5.

what is the soultion of the equation 2/5x+4=1/5

To solve the equation 2/5x + 4 = 1/5, we can start by isolating the variable x:

Subtract 4 from both sides:
2/5x = 1/5 - 4

Simplify the right side:
2/5x = 1/5 - 20/5

Combine the fractions on the right side:
2/5x = -19/5

To get rid of the fraction on the left side, we can multiply both sides by the reciprocal of 2/5, which is 5/2:
(5/2)(2/5x) = (5/2)(-19/5)

Simplify both sides:
(1)(x) = -19/2

The solution to the equation is x = -19/2. This is equivalent to x = -9.5.
