Solve for x . 3\7x−4=−1

Answer 1

To solve for x, we want to isolate x on one side of the equation.

Starting with the equation:

3/7x - 4 = -1

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

3/7x - 4 + 4 = -1 + 4

This simplifies to:

3/7x = 3

Next, we want to get rid of the 3/7 coefficient multiplying x.

Multiply both sides by the reciprocal of 3/7, which is 7/3:

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

This simplifies to:

x = 7

So the solution is x = 7.
