To solve for x, we can start by isolating the variable on one side of the equation. We can do this by first adding 4 to both sides of the equation:
3/7x - 4 + 4 = -1 + 4
This simplifies to:
3/7x = 3
To get rid of the fraction, we can multiply both sides of the equation by the reciprocal of 3/7, which is 7/3:
(3/7x) * (7/3) = 3 * (7/3)
On the left side, the 3's cancel out, and on the right side, 3 multiplied by 7 is 21:
x = 21
Therefore, x equals 21.
