Question

Make x the subject formula in the equation 3x + 6 - 3b​

Answer 1

x = b - 2

Explanation:

Given :

3x + 6 - 3b = 0

Subtract (6 - 3b) on both sides :

3x + 6 - 3b - (6 - 3b) = 0 - (6 - 3b)

3x + 6 - 6 + 3b - 3b = -6 + 3b

3x = 3b - 6

Divide throughout by 3 :

1/3 x 3x = 1/3 x (3b - 6)

x = b - 2

Answer 2

• 3x+6-3b=0
• 3x-3b+6=0
• 3(x-b)+6=0
• 3(x-b)=-6
• x-b=-6/3
• x-b=-2
• x=b-2

Done!
