for the first one, you would distribute so:
2.3 + 1.5 + .5x (if you don't know, for distribution, you would do .5 times 3 and .5 times x to get the answer that I got)
.5x + 3.8 (now you add 2.3 and 1.5 to get this answer)
So .5x + 3.8 is your final answer
now for the second question:
you combine the like terms so:
(2y + 5y) + (3x + 6x) <----- first step
(7y + 9x)*4
28y + 36x
I am pretty sure this is the right answer, but I can be wrong because of the way the equation is put in. does the * mean multiplication? If so, you can't get an addition of a number without variables.
Hope this helps!
