which method would be the simplest way to solve the system y=1/2x 2x+3y=28

1 answer

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.
