Question

1. 2 (x-3) = 9+ 3 (x-9)

Answer 1

x = 12

Explanation:

Given

2(x - 3) = 9 + 3(x - 9) ← distribute parenthesis on both sides

2x - 6 = 9 + 3x - 27, that is

2x - 6 = 3x - 18 ( subtract 3x from both sides )

- x - 6 = - 18 ( add 6 to both sides )

- x = - 12 ( multiply both sides by - 1 ), thus

x = 12

Answer 2

X=12

Explanation:

Distributing 2 over (x-3) on left hand side and 3 over (x-9) on right hand side we get.

2x-6=9+3x-27

Subtracting 2x and 9 from both hand sides and adding 27 ok both sides we get

27-9-6=3x-2x

12=x

Hence value of x is 12
