The following equation has an unknown (a) as one of its coefficients for x.

7x-9x-10=2(x-4)-ax

What value for a ensures that this equation has no solutions ?

alright
so 1st we will simplify this equation

$7x-9x-10=2(x-4)-ax $

anonymous · Answer

$7x-9x-10=2(x-4)-ax $

$-2x-10=2x-8-ax$

$-2x-10+2x=2x-8-ax+2x$

$-10=-8+4x-ax$ 

now if the 'a' becomes 4 then-

$-10=-8+4x-4x$
$-10=-8$

here this thing -> -10=-8 is false
so whatever value of x you take it will not satisfy the equation so a=4 is correct :)
