3/4(x+2)=6(x+12) Multiply both sides by 4 get 3(x+2)=24(x+12)

divide both sides by 3 get x+2=8(x+12)

or x+2=8x+96 subtract x from both sides 2=7x+96 subtract 96 from both sides

-94=7x divide both sides by 7 get -13 3/7=x

Distribute (3/4) to (x+2) AND distribute 6 to (x+12)

(3/4)x+(3/4)2=6(x)+6(12)

(3/4)x+(3/2)=6x+72

Now get anything with an x to ONE side. Subtract (3/4)x from BOTH sides AND subtract 72 from BOTH sides

(3/2)-72=6x-(3/4)x

Now simplify

-70.5=5.25x

x is NOT by itself just yet.

Divide BOTH SIDES by 5.25

-13.43=x
