2m - nx = x + 4 with description

Since x contains the variable to solve for, move it to the left side of the equation by subtracting x from both sides. 2m - n x - x = 4

Since 2m does not contain the variable to solve for, move it to the right side of the equation by subtracting 2m from both sides. n x - x = - 2 m + 4 Factor x out of - n x - x x (-n - 1) = - 2 m + 4 Divide each term by - n - 1 - n - 1 and simplify. x = 2 (m - 2) / n+1
