QuestionHow do you solve a question like, x-5=7?Community AnswerIn this example, move the 5 to the other side and change your action symbol, like this: x=7+5. Now, you can solve for x. To be sure you've done it correctly, put in your value for x in the original equation and solve.

QuestionHow do I solve -2 + (x-1)(x+2) = x(x-3) + 4(x-1)?DonaganTop AnswererThat equation has no solution, because it can be simplified to 4 = 4. That means the equation is true for all values of x, making it a "trivial" (useless) equation.

QuestionHow do I solve (2x + 1)(x - 2) - x(2x - 1) = 0?DonaganTop AnswererFirst perform the multiplication: (2x + 1)(x - 2) = 2x² - 4x + x - 2 = 2x² - 3x - 2 and (-x)(2x - 1) = -2x² + x. Then combine the two products and set the sum equal to zero: (2x² - 3x - 2) + (-2x² + x) = -2x - 2 = 0. Then -2x = 2, and x = -1.

QuestionHow would I solve 3x + 2 = 10 - 4(x - 1)?DonaganTop Answerer3x + 2 = 10 - 4x + 4 = 14 - 4x. Add 4x to both sides: 7x + 2 = 14. Subtract 2 from both sides: 7x = 12. x = 12/7.

QuestionHow do you solve this equation: 5x + 7y = 18?Community AnswerWhen you have one equation expressed in terms of two variables, all you can do is solve for one variable in terms of the other. In this case we can solve for x in terms of y, or y in terms of x. Let's do the former: first subtract 7y from both sides of the equation: 5x = 18 - 7y. Then divide both sides by 5: x = (18 - 7y) / 5. (In order to find numerical values for x and y, we would need a second independent equation also expressed in terms of x and y.)
