is that ment to be a > sign? well if it is3a>4a-5 (-4a)-a>-5 then just inverta>5
4a+5=25 4a=25-5 4a=20 a=20/4 a=5
6a - 8 - 4a - 2 → 6a - 4a - 8 - 2 → 2a - 10
5x - 8a + 4a - 2x + a = 3x - 3a
4a - 5b = 74a +5b = 17From the first equation:4a = 7 + 5bsubstitute this value in the second equation:7 + 5b + 5b = 177 + 10b = 1710b = 10b = 1Now,solve for a :4a - 5(1) = 74a = 7 + 54a = 12a = 3

a/7 + a/4 = 4a/28 + 7a/28 = 11a/28
Add them together: 3a+4a-a = 6a
7
4a+5=25 4a=25-5 4a=20 a=20/4 a=5
6a - 8 - 4a - 2 → 6a - 4a - 8 - 2 → 2a - 10
no
5x - 8a + 4a - 2x + a = 3x - 3a
21a - 6a
2b+b-4
3a * * * * * Actually, it is 4a.
Without any signs between what appear to be terms, it is not possible to simplify.
