Question

The value of 2x + 2y, for x = 7 and y = 3, is 50.

True
False

Answer 1

Salutations!

This equation is substituting variables, means that instead of the variable you need to enter the given number.


`2x+2y=20`

Where as
`x =7` and
`y = 3`


`2*7 +2*3=50`


`2*7=14`


`2*3=6`


`14+6=20`

Thus, the answer is false! After all the calculation you get the answer as
`20`

Hope I helped (:

Have a great day!

Answer 2

False, the answer would be 20.

2(7) + 2(3)

14 + 6

20
