4X + 7Y = 60
-4X + 7Y = - 4
-----------------------+
14Y = 56
Y = 4
---------
insert back into one of these equations to find X
4X + 7(4) = 60
4X + 28 = 60
4X = 32
X = 8
------------check
4(8) + 7(4) = 60
32 + 28 = 60
60 = 60
----------------checks, now second equation
-4(8) + 7(4) = -4
-32 + 28 = -4
-4 = -4
--------------checks
solution set.
X = 8
Y = 4

Plug your ordered pair into both of your equations to see if you get they work.
Do you mean: 4x+7y = 47 and 5x-4y = -5 Then the solutions to the simultaneous equations are: x = 3 and y = 5
That would be the "solution" to the set of equations.
It works out that x = 6 and y = 3 or as (6, 3)

Plug your ordered pair into both of your equations to see if you get they work.
As there is no system of equations shown, there are zero solutions.
Do you mean: 4x+7y = 47 and 5x-4y = -5 Then the solutions to the simultaneous equations are: x = 3 and y = 5
By elimination: x = 3 and y = 0
That would depend on the given system of linear equations which have not been given in the question
That would be the "solution" to the set of equations.
x = -3/5 and y = -24/5
It works out that x = 6 and y = 3 or as (6, 3)
