꧁Holi꧂

$3(x - 1) + 5(x - 2) - (x - 3) = 18$

$3x - 3 + 5(x - 2) - (x - 3) = 18$

$3x - 3 + 5x - 10 - (x - 3) = 18$

$3x - 3 + 5x - 10 - x + 3 = 18$

$3x + 5x - 10 - x = 18$

$7x - 10 = 18$

$7x = 18 + 10$

$7x = 28$

$x = 4$

Answer 2

3(x-1) + 5(x-2) - (x-3) = 18

3x - 3 + 5x - 10 - x + 3 = 18

3x + 5x - x - 3 - 10 + 3 = 18

8x - x - 13 + 3 = 18

7x  - 10 = 18

7x = 18 + 10

7x  = 28

x= 28/7

x = 4
