Answer 1

This is an equation in x. We need to use distribution property to simplify and use algebra to solve for x.

Process shown below.

`\begin{gathered} -3\mleft[x+5\mright]+1=7\mleft[x+5\mright]+8 \\ -3x-15+1=7x+35+8 \\ -3x-14=7x+43 \\ -14-43=7x+3x \\ -57=10x \\ x=-(57)/(10) \\ x=-5.7 \end{gathered}`
