3x+3/2+3=3-12x+18

Answer 1

Hi Shamiera,

The goal here is to combine like terms and solve for X. 3x+3/2+3=3-12x+18

3/2 + 3 = 3/2 + 6/2 = 9/2

and 3 + 18 = 21 We therefore have 3x + 9/2 = -12x + 21. Now add 12x to both sides

+12x. +12x

15x + 9/2 = 21. Subtract 9/2 from both sides and you get

15x = 21 - 9/2. get common denominator so that you can subtract the fractions

15x = 42/2 - 9/2

15x = 33/2. Now you multiply both sides by 1/15 (divide by 15)

X = 33/2 * 1/15

X = 11/10

I'm guessing you probably need to review working with fractions.

I hope this helps.
