a) 2x + 5 - 3x = x + 19
c) 11 + 2x = 6x – 3 + 3x
ex-1- 4x=5-3x-6
b) 7x - 2x = 2x + 1 + 3x
d) 7 + 5x - 2 = x-3 + 2x
f) 5x = 4 - 3x + 5 - X​

Answer 1

3x – 1 = 2 3x = 2 + 1 => 3x = 3 => x = 3/3 => x = 1 2x – 5 = x + 2 2x ... </li></ul>- 3 ( 2x + 1 ) + 5 ·( - x + 6 ) = 7 - 6x – 3 – 5x + 30 = 7 - 6x – 5x = 7 - 30 + ... 1 ○ x – 2 ○ (4x – 5) = 3 ○ 3x x – 8x + 10 = 9x - 16x = -10 => - 7x – 9x = -10; 24.
