<span>7x-4y=-7
5x+y=22
multiply 4 on the 2nd equation
</span>20x+ 4y=88
now you have
7x -4y = -7
20x + 4y = 88
--------------------add
27x = 81
x = 3
7x-4y=-7
7(3)-4y=-7
-4y = -28
y = 7
answer (3, 7) is the solution
No. The whole numbers are the natural numbers (counting numbers, 1, 2, 3...), but starting with zero instead of one. -1 is an integer but not a whole number.
The answer would be A) X=5
