To solve the equation -3/(x+1)=4/(x-1), you can start by cross-multiplying to eliminate the fractions. This gives you -3(x-1) = 4(x+1). Simplifying further, you get -3x + 3 = 4x + 4. Combine like terms by adding 3x to both sides, which gives you 3 = 7x + 4. Subtract 4 from both sides to isolate the variable, resulting in -1 = 7x. Finally, divide both sides by 7 to solve for x, giving you x = -1/7.
