Question

please help solve the following and please show your work .5(2-x) = 1.5x+7

Answer 1

multiply both sides by 10 to clear the annoying decimal. you get
\[5(2-x)=15x+70\] (don't forget to multiply the 7 by 10 as well)

Answer 2

then it is straighforward
\[10-5x=15x+70\]
\[-60=20x\]
\[x=\frac{-60}{20}=-3\]
