To solve for x in the equation 3/7x - 4 = -1, we can start by adding 4 to both sides to isolate the variable:
3/7x - 4 + 4 = -1 + 4
3/7x = 3
Next, we can multiply both sides of the equation by 7 to get rid of the fraction:
7 * (3/7x) = 7 * 3
3x = 21
Now, divide both sides of the equation by 3 to solve for x:
(3x)/3 = 21/3
x = 7.
Therefore, the solution is x = 7.
