Hey there, Caydog!
So let's solve this.
Step 1: Simplify both sides of the equation.
\(5−2(4a+1)+3a=13\)
\(5+(−2)(4a)+(−2)(1)+3a=13\) (Distribute)
\(5+−8a+−2+3a=13\)
\((−8a+3a)+(5+−2)=13\) (Combine Like Terms)
\(−5a+3=13\)
Step 2: Subtract 3 from both sides.
\(−5a+3−3=13−3\)
\(−5a=10\)
Step 3: Divide both sides by -5.
\(\frac{-5a}{-5}=\frac{10}{-5}\)
Therefore a=-2.
Hope this helped! :)
