$\blacksquare$ 3x = 2x + 18

➨ 3x - 2x = 18

➨ x = 18

━━━━━━━━━━━━━━━━━━

$\blacksquare$ 5t - 3 = 3t - 5

➨ 5t - 3t = 3 - 5

➨ 2t = -2

➨ t = -1

━━━━━━━━━━━━━━━━━━

$\blacksquare$ 5x + 9 = 5 + 3x

➨ 5x - 3x = 5 - 9

➨ 2x = -4

➨ x = -2

━━━━━━━━━━━━━━━━━━

$\blacksquare$ 4z + 3 = 6 + 2z

➨ 4z - 2z = 6 - 3

➨ 2z = 3

➨ z = $\large\frac{3}{2}$

━━━━━━━━━━━━━━━━━━

$\blacksquare$ 2x - 1 = 14 - x

➨ 2x + x = 14 + 1

➨ 3x = 15

➨ x = 5

━━━━━━━━━━━━━━━━━━

$\blacksquare$ 8x + 4 = 3(x - 1) + 7

➨ 8x + 4 = 3x - 3 + 7

➨ 8x - 3x = 4 - 4

➨ 5x = 0

➨ x = 0
