Encontre as raízes da equação incompleta pelo método da fatoração: 3x² - 27 =0 * 2 e -2
2,5 e -2,5
3 e -3
5 e -5
-4 e 4

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
