Answer:
2a + 30
Step-by-step explanation:
break it down so it is 4(a+5)
then work out -2(a-5)
so 4 x a then 4 x 5 which gives 4a + 20
then -2 x a then -2 x -5 which gives -2a + 10
then when you have 4a + 20 -2a + 10
do 4a - 2a which is 2a
do 20 + 10 which is 30
so the answer comes to 2a + 30

-3 is actually less than -1
it can't be equal because they are 2 different values
and it can't be greater than because if you place -3 and -1 in a number Line, -1 is closer to 0 which equals that -1 is greater than -3
