x = 118/19x=11819

Explanation:

First, expand by multiplying 33 by every term in the brackets. Then group together the terms with xx in them and group the terms without xxs in them together.

Finally, divide the number in front of the xx by the number on the other side to solve for xx.

3 (2x + 3x + 2) = -4x + 1243(2x+3x+2)=4x+124

3*2x + 3*3x + 3*2 = -4x + 12432x+33x+32=4x+124

6x + 9x + 6 = -4x + 1246x+9x+6=4x+124

15x + 6 = -4x + 12415x+6=4x+124

15x + 4x = 124 - 615x+4x=1246

19x = 11819x=118

x = 118/19 = 6.21x=11819=6.21
