Answer 1

To solve for x, we can start by isolating the variable on one side of the equation.

3/7x - 4 = -1

First, we add 4 to both sides of the equation to get rid of the constant term on the left side:

3/7x = 3

Next, we can multiply both sides of the equation by the reciprocal of 3/7, which is 7/3, to isolate x:

(7/3) * (3/7)x = (7/3) * 3

Simplifying the left side:

x = 7

Therefore, x equals 7.
