Answer:

b = - 0.389

Step-by-step explanation:

38/99=b+17/22

to solve this  expression we would make b the subject of the formulae

and evaluate the other parameters.

38/99=b+17/22

collect the like terms

38/99 - 17/22 = b

22( 38) - 99 (17)/ 2178 = b

836 - 1683/2178 = b

-847/2178 = b

b = - 0.389
