To solve for x, we first need to isolate x on one side of the equation.
Add 4 to both sides to get rid of the -4:
3/7x - 4 + 4 = -1 + 4
3/7x = 3
Now, to isolate x, we need to multiply both sides by 7/3:
3/7x * 7/3 = 3 * 7/3
x = 21/3
x = 7
Therefore, the solution to the equation 3/7x - 4 = -1 is x = 7.
3/7x -4= -1
