See a solution process below:

First, multiply the two numbers on the left of the equation:

#2 * -1/2 + y = 0#

#-2/2 + y = 0#

#-1 + y = 0#

Now, add #color(red)(1)# to each side of the equation to solve for #y# while keeping the equation balanced:

#color(red)(1) - 1 + y = color(red)(1) + 0#

#0 + y = 1#

#y = 1#
