x2 - 2x + 12 = 5x + 2
rearrange & group all term on one side (i.e, subtract 5x & 2 from both sides) & you'll get the following equation:
x2-7x+10 = 0
what two factors of +10 added together equals -7, (-5,-2), so
(x-5)(x-2) = 0
so, x=5 & x=2
zero solutions. If you plot these two lines, you will see that they are parallel and do not intersect.
since a=5 you can put that into your equation of a+7=12 a=5 a+7=12 5+7=12 12=12 Correct So yes the given number is a solution to the given equation
The equation seems to equal 72.

The equation -7 plus 12 equals out to be five. This is a math problem.
It is: y = -4x+12
-0.5
y = 10
There is no equation. An equation is true, whereas the statement ( 5 + 7 = -12 ) is false.
None because without an equal it is not an equation. But if it was in the form of x2+7x+12 = 0 then it would have 2 solutions which are x = -3 and x = -4
