would I have both of 1h together since the 15.3 is on the opposite side of the= sign

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
