Solution:
The equation is an algebraic equation with variables on both sides.
Given:
[tex]15.3+1h=1.3-1h[/tex]
To solve for the unknown, we collect the like terms;
[tex]\begin{gathered} 1h+1h=1.3-15.3 \\ 2h=-14 \\ \text{Dividing both sides by 2,} \\ h=-\frac{14}{2} \\ h=-7 \end{gathered}[/tex]
Therefore, the value of h is -7
