Question

Enter the value of b when the expression 8/9x+b is equivalent to 1/9 (8x+5)

Answer 1

b = 5 / 9

Explanation:

8/9x + b = 1/9(8x + 5)

Make b the subject of formula.

b = 1/9 (8x + 5) - 8/9x

Multiply through by 9

9b = 9 * 1/9 ( 8x + 5) - 9 * 8/9x

9b = 8x + 5 - 8x

9b = 5

b = 5 / 9

The value of b = 5 / 9
