Firstly, we need to expand the brackets on the right. Can you do that for me?

1.5x+6=3x-15 @tom982

Not quite. \[3(2.5x-6)=3*2.5x-3*6\] Do you see why it's wrong?

1.5x + 6 = 7.5x - 18 (we multiply the values inside the brackets) 6 + 18 = 7.5x - 1.5x (we transfer the 18 on the other side and 1.5x on the one) 24 = 6x (sum up both numbers) 4 = x (divide) This should help :)

First u need to expand the bracket. second shif all the x to the left hand side. Then divide both sides. \[1.5x+6=3(2.5x-6)\]

  • anonymous
\[1.5x+6=7.5x-18\]
anonymous
  • anonymous
\[1.5x-7.5x=-18-6\]

\[-6x=-24\]

Then divide -6 on both sides.

\[\frac{ -6 }{ -6 }x=\frac{ -24 }{ -6 }\]
