Double Double · Answer 1

R = 4 x + 8y [ Given ]

when,

x = 4 and R = 32

★ Substituting the values

=> 32 = 4 * 4 + 8y

=> 32 = 16 + 8y

=> 8y = 32 - 16

=> 8y = 16

=> y = 8/16

=> y = 2

Step-by-step explanation:

R=4x+8y

(substitute given values)

32=4*4+8y

32=16+8y

32-16=8y

16/8=y

2=y

hence answer is 2
