Solve for x.
3/7x−4=−1
To solve for x, we need to isolate x on one side of the equation.
First, add 4 to both sides to get rid of the -4 on the left side of the equation:
3/7x = 3
Next, multiply both sides by 7 to get rid of the fraction:
7 * (3/7x) = 7 * 3
3x = 21
Finally, divide by 3 on both sides to solve for x:
x = 21/3
x = 7
Therefore, x = 7.
