Resuelva las siguientes ecuaciones lineales, haga la prueba para cada una. 1. 2x + 14 = 0 2. 3x – 5 = 0 3. 7z + 8 = – 6 4. – 5w + 1 = 2 5. 7(y +1) – 2 = 5 (y + 1) +2 6. 7. X – (4 – x) = 5( x + 1) + x 8. 2 – 6t + 2( 3 – t ) = ( t – 3) 5 – 3 9. 10. p² + 4p – 2 = p² – p + 8 11. 4 (x – 10 ) = – 6 ( 2 – x ) – 6x 12. 2(x + 1) – 3 ( x – 2) = x + 6 13. 14. 15. Considere lo siguiente x = – 1 x² +x = x²– 1 x( x +1 ) = ( x – 1) ( x +1) x = x – 1 0 = – 1
