WebFeb 24, 2024 · Solution: Given: 4x + 2y =10 ⇢ (1) 5x − y = 4 ⇢ (2) In order to solve the given equations by elimination, the coefficients of one of the variables must be equal. Therefore, multiply the first equation by 1,and multiply the second … WebJan 13, 2024 · The solution for this system is the ordered pair ( − 3, − 1). Let’s practice the substitution method by looking at one more problem together: y = − 2 x + 4. 3 x + 2 y = 1. Because y is solved in terms of x in the first equation, substitute the expression ( − 2 x + 4) for y in the second equation. 3 x + 2 ( − 2 x + 4) = 1. WebNov 7, 2024 · You continue this elimination process again until you have solved for all of your variables.
