Question

Evaluate 2x + 6y when x = -4/5 and y= 1/3

Answer 1

= 2 * (-4/5) + 6 * 1/3

= - 8/5 + 2

= - 8/5 + 10/5

= 2/5

= 0,4

* = multiply

Answer 2

`(2)/(5)\\`

Explanation:

`2x + 6y`

`2(-(4)/(5)) + 6((1)/(3)) \\\\(2)/(1) (-(4)/(5)) + (6)/(1) ((1)/(3))\\\\-(8)/(5)+ (6)/(3)\\\\-(24)/(15)+ (30)/(10)\\\\(6)/(15)\\\\(2)/(5)`

Hope this helps!
