Explicación paso a paso:

1.R/ 3 + 3x - 1 = x + 2 + 2x ---- 2 + 3x = x + 2 + 2x ----- x + 2x ------ 1x + 2x -------- (1 + 2) x ----- 3x ----- 2 + 3x = 3x + 2 ------x E R

2.R/ 2 (1 + 2x) = 10 ------ 2 (1 + 2x) ÷ 2 = 10 ÷ 2 ----- 1 + 2x = 10 ÷ 2 ----- 1 + 2x = 5 ----- 1 + 2x - 1 = 5 - 1 ----- 2x = 5 - 1 ----- 2x = 4 ---- 2x ÷ 2 = 4 ÷ 2 ----- x = 4 ÷ 2 ---- X = 2

3.R/ 2 (3x - 2) = - 2 ----- 2 (3x - 2) ÷ 2 = - 2 ÷ 2 ------ 3x - 2 = - 2 ÷2 ------- 3x - 2 = - 1 ----- 3x - 2 + 2 = - 1 + 2 ----- 3x = -1 + 2 ----- + ( 2 - 1 ) ---- 1 ----- 3x = 1 ----- 3x ÷ 3 = 1 ÷ 3 ------ x = 1 ÷ 3 ----- x = 1/3

4.R/ - 2 (3x - 2) = - 2 ----- - 2 (3x - 2) ÷ (- 2) = -2 ÷ (-2) ----- 3x - 2 = -2 ÷ (-2) ------ 3x - 2 = 2 ÷ 2 ----- 3x - 2 = 1 ----- 3x - 2 + 2 = 1 + 2 ----- 3x = 1 + 2 ---- 3x = 3 ---- 3x ÷ 3 = 3 ÷ 3 ---- x = 3 ÷ 3 ----- x = 1

5.R/ 1 - x/3 = 5x/3 ----- 3 ( 1 - x/3) = 3 x 5x/3 ----- 3 - 3 x x/3 = 3 x 5x/3 ----- 3 - 3 x x/3 = 5x ----- 3 - x = 5x ---- 3 - x - 3 = 5x - 3 ---- - x = 5x - 3 ----- - x - 5x = 5x - 3 - 5x ----- - x - 5 x = -3 ------ -x - 5 x ---- -1x - 5x ----- (-1 - 5) x ----- - 6x ---- - 6x = - 3 ---- -6x ÷ (-6) = - 3 ÷ (-6) ---- x = - 3 ÷ (-6) ----- x = 3 - 6 ----- x = 3/6 ---- x = 1/2
