Solve each problem by forming a pair of simultaneous equations: 1. Find two numbers with a sum of 15 and a difference of 4. 2. Twice one number added to three times another gives 21. Find the numbers, if the difference between them is 3. 3. The average of two numbers is 7. and three times the difference between them is 18. Find the numbers.
For the second equation with (-1, -5), we have -5 = 1 - 6 => -5 = -5 So (-1, -5) is a solution to the above equations Now for the second equation with (0, -2), we have -2 = 3(0) - 2 => -2 = -2 For the second equation with (0, -2), we have -2 = 0 - 6 => -2 ≠ -6 So (0, -2) is not a solution to the above equations

"Full Coverage": Simultaneous Equations This worksheet is designed to cover one question of each type seen in past papers, for each ... Categorisation: Solve linear simultaneous equations where the coefficients are different, and both second coefficients are negative. [Edexcel GCSE(9-1) Mock Set 3 Autumn 2017 1F Q24, 1H Q5]
the equations by the same number the equation remains valid. We can then get the same number of xs or ys in two equations. 2 x (B) = 2x + 10y = 34 (C) Now we have the same number of xs in equation (A) and (C) so when we subtract one from the other there are no x terms left. 2x + 10y = 34 (C) - (2x + 3y) = 13 (A) 7y = 21
