Answer 1

Answer:18

Explanation:

Answer 2

Explanation:

17 X (18-x)+12 X x= 271

multiply 17 x 18 and 17 X x also multiply 12 X x

17x18=306

17Xx= 17x

12Xx=12x

equation now looks like after solving:

306-17x+12x=271

combine like terms:

306-5x=271

subtract 306 from both sides

-5x=-35

get x by itself by dividing -5 from both sides

x= -35/-5 which equals 7

x=7

So you will 7 family devotional books and 11 youth devotional books
