Question

Given that r = 7x +5y find y when x =9 and R=35

Answer 1

Answer:

r = 7x +5y  as r = 35 and x = 9

=>  35 = 7 * 9 + 5y

=>  5y = 35 - 63

=>  5y = (-28)

=>   y =  $(-\frac{28}{5} )$

Please add as BRAINLIEST if it is correct and sorry if it is wrong.

Answer 2

Step-by-step explanation:

35=7×9+5y
