[tex]20.2=-\frac{x}{0.2}+3.7[/tex]
To solve for x:
1. substract 3.7 in both sides of the equation:
[tex]\begin{gathered} 20.2-3.7=-\frac{x}{0.2}+3.7-3.7 \\ \\ 16.5=-\frac{x}{0.2} \end{gathered}[/tex]
2. Multiply both sides of the equation by 0.2:
[tex]\begin{gathered} 0.2\cdot16.5=-\frac{x}{0.2}\cdot0.2 \\ \\ 3.3=-x \end{gathered}[/tex]
3. Multiply both sides of the equation by -1:
[tex]\begin{gathered} (-1)\cdot3.3=(-1)\cdot(-x) \\ -3.3=x \end{gathered}[/tex]Then, x is -3.3
