Substitute y=1/2x into the second equation:
2x + 3(1/2)x = 28
2x + 3/2x = 28
Multiplying the entire equation by 2 to get rid of the fraction:
4x + 3x = 56
7x = 56
x = 8
Now, substitute x=8 back into the first equation to solve for y:
y = 1/2 * 8
y = 4
So, the solution to the system y=1/2x and 2x+3y=28 is x=8, y=4.
which method would be the simplest way to solve the system y=1/2x 2x+3y=28
