Answer 1

Answer:

$1) \: 7(x + 3) = 5(2x - 3) \\ \\ = > 7x + 21 = 10x - 15 \\ \\ = > 7x - 10x = - 15 - 21 \\ \\ = > - 3x = - 36 \\ \\ = > 3x = 36 \\ \\ = > x = \frac{36}{3} \\ \\ = > x = 12$

$2) \: 5x - 13 = 2x + 8 \\ \\ = > 5x - 2x = 8 + 13 \\ \\ = > 3x = 21 \\ \\ = > x = \frac{21}{3} \\ \\ = > x = 7$

$3) \: 17x + 12 = 13x + 24 \\ \\ = > 17x - 13x = 24 - 12 \\ \\ = > 4x = 12 \\ \\ = > x = \frac{12}{4} \\ \\ = > x = 3$

hope this much helps uh ❣️
