If you meant (x/5) + 2 = 3
x/5 = 1
x =5
-----------------
If you meant x/(5+2) = 3
x/(7) = 3
x = 21
10
14
it is 7
That is not a correct equation. The numbers on the left equal -16, not 0. This is an equation with no solution.
17
10
It does not, this equation is false.
Since there is no x in the equation, it can equal anything at all!
2+2/x/2+2/x^2=2+1/x+2/x^2

y = 2
it is 7
That is not a correct equation. The numbers on the left equal -16, not 0. This is an equation with no solution.

1 + 1 = 2
The left hand side of the equation in the question is 42 * 2 + 16 / 2 * 4 This equals 16*2 + 16/2*4 = 32 + 32 = 64 which does not equal 10.
