To solve for x, let's first isolate the variable on one side of the equation.
The given equation is 3/7x - 4 = -1.
Let's add 4 to both sides of the equation:
3/7x - 4 + 4 = -1 + 4
3/7x = 3
Next, we need to get rid of the fraction by multiplying both sides of the equation by the reciprocal of 3/7, which is 7/3:
(3/7x) * (7/3) = 3 * (7/3)
x = 21/3
Simplifying the right side of the equation:
x = 7
Therefore, the solution to the equation is x = 7.
solve for x
3/7x-4=-1
