Answer 1

Step-by-step explanation:

$3.) \: 2x + 1 = 5 \\ = > 2x = 5 - 1 \\ = > 2x = 4 \\ = > x = \frac{4}{2} \\ = > x = 2 \\ \\ \\ 4.) \: \: \: 3x + 4 = 7 + 2x \\ = > 3x - 2x = 7 - 4 \\ = > x = 3 \\ \\ \\ 5.) \: - 4 - 2x = x + 5 \\ = > - 2x - x = 5 + 4 \\ = > - 3x = 9 \\ = > x = \frac{9}{ - 3 } \\ = > x = - 3 \\ \\ 6.)2x + 7 = 5x - 5 \\ = > 2x - 5x = - 5 - 7 \\ = > - 3x = - 12 \\ = > x = \frac{ - 12}{ - 3} \\ = > x = 4 \\ \\ 7.)3y + 4 = 10 \\ = > 3y = 10 - 4 \\ = > 3y = 6 \\ = > y = \frac{6}{3} \\ = > y = 2 \\ \\ 8.)4y + 3 = 2y + 9 \\ = > 4y - 2y = 9 - 3 \\ = > 2y = 6 \\ = > y = \frac{6}{2} \\ = > y = 3$
