[tex]\text {To solve this problem here's what you do}[/tex]
[tex]\text {Simplify the equation:}[/tex]
[tex]\text {(-2)(1)+(-2)(-4x)=3x+8 (Distribute)}[/tex]
[tex]\text {-2+8x=3x+8}[/tex]
[tex]\text {8x-2=3x+8}[/tex]
[tex]\text {Now you will want to Subtract 3x:}[/tex]
[tex]\text {8x-2-3x=3x+8-3x}[/tex]
[tex]\text {5x-2=8}[/tex]
[tex]\text {Next Step is to Add 2:}[/tex]
[tex]\text {5x-2+2=8+2}[/tex]
[tex]\text {5x=10}[/tex]
[tex]\text {Final Step is to Divide 5:}[/tex]
[tex]\text {5x/5=10/5}[/tex]
[tex]\text {Your answer will be:}[/tex]
[tex]\framebox {x=2}[/tex]
