Answer:
[tex]h=4[/tex]Explanation: We need to solve for h in the given equation, which is:
[tex]15h-13h-h+3=7[/tex]Isolating unknowns and constants:
[tex]\begin{gathered} 15h-13h-h+3=7\rightarrow15h-14h+3=7 \\ \therefore\rightarrow \\ 15h-14h=7-3=4 \\ \therefore\rightarrow \\ 15h-14h=4 \end{gathered}[/tex]Simplifying gives:
[tex]\begin{gathered} 15h-14h=4 \\ \therefore\rightarrow \\ h=4 \end{gathered}[/tex]
