solve for x a⋅(5-x)=bx-8

Answer 1

Answer 2

Hi,

a⋅(5-x)=bx-8

1) distribute: 5a -ax = bx -8

2) all terms include x must be at the left and other right

-ax -bx = -5a -8 Both side times (-1) (optional) for getting rid of negative coefficient

ax + bx = 5a + 8 left side factor of x

x( a + b ) = 5a + 8 Both sides divide by coefficient of x it means (a+b)

x= ( 5a +8 ) / ( a + b)

I hope it is useful.
