respondam a que vcs souberem pf :D

Answer 1

$d)\\ 2x + 3 = x + 4 \\ \\2x -x = 4 - 3 \\ \\ x = 1 \\ \\ e)\\ \\ 4x - 10 = 2x + 2 \\ \\ 4x - 2x = 2 + 10\\ \\ 2x = 12 \\ \\ x = \frac{12}{2}\\ \\x = 6 \\ \\ g)\\ \\ 2x + 5 -5x + 2 = 0\\ \\2x -5x = -2 - 5\\ \\ -3x = -7 (-1)\\ \\ 3x = 7 \\ \\ x = \frac{7}{3}\\ \\h) \\ \\5 + 6x = 5x + 2 \\\\ 6x - 5x = + 2 - 5 \\ \\ x = -3$

$i)\\ x + 2x - 1 - 3 = x \\ \\ x + 2x -x = 3 + 1 \\ \\2x = 4\\ \\ x = \frac{4}{2}\\ \\ x = 2\\ \\j)\\5x -5 +x = 9 + x\\ \\ 5x + x -x = 9 + 5 \\ \\5x = 14\\ \\ x = \frac{14}{5}\\ \\l)\\7x-4-x=-7x+6+15\\ \\ 7x - x + 7x = 6 + 15 + 4 \\ \\13x = 25 \\ \\x = \frac{25}{13}m)\\2-3=-2x+12-3x\\ \\ 2x +3x = 12 - 2 + 3 \\ \\ 5x = 13\\ \\x =\frac{13}{5}$
