Answer:
The value of x is;
[tex]x=3[/tex]
Explanation:
Given the equation;
[tex]0.7+0.2x=1.3[/tex]
Solving for x;
[tex]\begin{gathered} 0.7+0.2x=1.3 \\ \text{subtract 0.7 from both sides;} \\ 0.7-0.7+0.2x=1.3-0.7 \\ 0.2x=0.6 \end{gathered}[/tex]
so, we have;
[tex]\begin{gathered} x=\frac{0.6}{0.2} \\ x=3 \end{gathered}[/tex]
Therefore, the value of x is;
[tex]x=3[/tex]
