Solve for x

3/7x -4 = -1

1 answer

To solve for x, you would need to isolate x on one side of the equation.

Given the equation:
3/7x - 4 = -1

First, add 4 to both sides of the equation to move the -4 to the right side:
3/7x - 4 + 4 = -1 + 4

Simplifying:
3/7x = 3

To get rid of the fraction, you can multiply both sides of the equation by the reciprocal of 3/7, which is 7/3:
(7/3)(3/7x) = (7/3)(3)

Simplifying:
1x = 7

Therefore, x = 7.
