[tex]x-5(x+1)=3x+2[/tex]
1. Remove parenthesis: Distributive property (a(b+c)=ab+ac)
[tex]x-5x-5=3x+2[/tex]The error is in the line 1.
2. Combine like terms:
[tex]-4x-5=3x+2[/tex]
3. Substract 3x in both sides of the equation:
[tex]\begin{gathered} -4x-3x-5=3x-3x+2 \\ \\ -7x-5=2 \end{gathered}[/tex]
4. Add 5 in both sides of the equation:
[tex]\begin{gathered} -7x-5+5=2+5 \\ \\ \\ -7x=7 \end{gathered}[/tex]
5. Divide into -7 both sides of the equation:
[tex]\begin{gathered} \frac{-7}{-7}x=\frac{7}{-7} \\ \\ x=-1 \end{gathered}[/tex]
