Solution:
Given the expression below
[tex]8(1-5x)=13[/tex]To find the value x,
Open the brackets and solve for x
[tex]\begin{gathered} 8(1-5x)=13 \\ 8-40x=13 \\ Collect\text{ like terms} \\ -40x=13-8 \\ -40x=5 \\ Divide\text{ both sides by -40} \\ \frac{-40x}{-40}=\frac{5}{-40} \\ x=-\frac{1}{8} \end{gathered}[/tex]Hence, the value of x is -1/8
