Step-by-step explanation:
if x = 7 and y = 4
a) x + 2y
= 7 + 2 . 4
= 7 + 8
= 15
b) (2x - y)/5
= (2 . 7 - 4)/5
= (14 - 4)/5
= 10/5
= 2
#CMIIWОтвет:
The first equation is 15 and the second equation is 2.
Step-by-step explanation:
You have to use substitution. For the first equation it would be: 7 + 2(4),which is 7 + 8,which is 15. For the second equation it would be: 2(7) - 4 divided by 5,which is also 14 - 4 divided by 5,which is 10/5, which is 2.
