Answer:

(g + h)(a) = 9

Step-by-step explanation:

g(a)= 4a +4

h(a)= -4a + 5

(g + h)(a)

We add the functions

(g + h)(a) = 4a +4 + -4a + 5

Combine like terms

(g + h)(a) =0a +9

(g + h)(a) = 9

Y= 4x+3<br> Y=-3x-2<br> Substitution or elimination

Elimination would be the best way to answer this question because you can multiply the top by 3 and the bottom by -4

Please help me I tried to do it

You do 9x27=243 then take 2x31=62 add 243+62=305 then take 305 and subtract it from 28 305-28=277
so if i did it right you should get n=277
