Study Notes

Equations de Algebra

x + 8 = 16: Solve per subtractar 8 de ambos lateres; resulta in x = 8.
2x + 5 = 9: Subtract 5; resulta in 2x = 4, ergo x = 2.
-9x = 9: Divide per -9; resulta in x = -1.
2x - 6 = -8: Add 6; resulta in 2x = -2, ergo x = -1.
3x = -24: Divide per 3; resulta in x = -8.
5x + 6 = 16: Subtract 6; resulta in 5x = 10, ergo x = 2.
3x = 6: Divide per 3; resulta in x = 2.
-x + 5 = 10: Subtract 5; resulta in -x = 5, ergo x = -5.
7x + 3 = 24: Subtract 3; resulta in 7x = 21, ergo x = 3.
-8x = -8: Divide per -8; resulta in x = 1.
2x = 14: Divide per 2; resulta in x = 7.
2x - 9 = -19: Add 9; resulta in 2x = -10, ergo x = -5.
