Answer:
[tex]y=-16[/tex]
Step-by-step explanation:
The expression is written:
[tex]-y/2+5=13[/tex]
We multiply the whole expression by 2 to get rid of the fraction:
[tex]-y+5\cdot(2)=13\cdot(2)[/tex]
[tex]-y+10=26[/tex]
We move -y to the right hand side to make it positive y and move 26 to the left side to subtract it from 10:
[tex]10-26=y[/tex]
[tex]y=-16[/tex]
