Answer 1

The most efficient method to solve this system of equations would be substitution.

First, rearrange the equation y = x to x = y. Then substitute x = y into the second equation:

2x + 3y = 28
2(y) + 3y = 28
2y + 3y = 28
5y = 28
y = 28/5
y = 5.6

Now substitute the value of y back into the equation x = y:

x = y
x = 5.6

Therefore, the solution to the system of equations is x = 5.6 and y = 5.6.
