Answer 1

Answer:

8

Step-by-step explanation:

(5+5×3.2)+3-5×3.2

5+16+3-16

24-16

8....

Answer 2

Answer:

-1. 9

Step-by-step explanation:

a=5

b= 3.2(a+ab)+ 3 - ab......(equation 1)

substitute value of a in equation 1

b= 3.2(5+5b)+3-5b

b= 3.2×5+ 3.2×5b +3 -5b

b= 16+ 16b +3-5b

b= 19+ 11b

10b= -19

b= -19/10 = -1.9
