To solve for x in the equation 3/7x - 4 = -1, we will first distribute the 3/7 to the x term.
(3/7)x - 4 = -1
Next, we will add 4 to both sides of the equation to isolate the x term on the left side.
(3/7)x = -1 + 4
(3/7)x = 3
To solve for x, we need to get rid of the coefficient of 3/7. We can do this by multiplying both sides of the equation by the reciprocal of 3/7, which is 7/3.
(7/3)(3/7)x = (7/3)(3)
x = 7/3
Therefore, the solution for x is x = 7/3.
Solve for x . 3/7x−4=−1
