Algebra Help Two Variables
Please help I have a midterm tomorrow!?
Question: How do you solve the following system by addition method? (Linear equations and inequalities in two variables — Algebra 2) 3 y = 2x – 3x 2-2y = 10 please give me step by step …. I am having a problem with numbers to find out Multiples in the equation for first and second. How I can find out multply numbers. Thanks!
And it has opposite signs in both equations and our goal is to get the same term and the coefficient of the two equations with opposite signs. 2 * (2x 3 =- 2) becomes 4x =- 4 6 3 * (3x-2y = 10) becomes 9x-6y = 30 Add the two equations: (9 x 4 x) + (6y-6y) = (-4 +30) 13X = 26 x = 2 x plug in and for two (2) and 3 =- 2 4 3 and 2 =- 3y =- 6 =- 2 Edition: Allen is near, but he erred on the right side of the equation here (10 should be 30) "Now I add the first equation and quadratic equation … 9 x 6 and 4x-6y =- 4 +10 "Plug in x = 2, and =- 2 in any of the equations for the proof that my solution is correct.
