If the question is to solve 3a + 20 = 4a + 5 then a = 15.
3a + a = 4a Example: a = 5 (3x5) + 5 = 15 + 5 = 20 = 4 x 5
It is: 7a+1 when simplified
3a-9 = 6 3a = 6+9 3a = 15 a = 15/3 a = 5 Substitute a = 5 into 4a-1. 4a-1 =4(5)-1 =20-1 =19 Therefore, the value of 4a-1 is 19.
a < -12
4a+5=25 4a=25-5 4a=20 a=20/4 a=5
a(4a - 3)(3a - 5)
4a - 5 = 7a - 7 -5 = 3a - 7 2 = 3a a = 3/2
is that ment to be a > sign? well if it is3a>4a-5 (-4a)-a>-5 then just inverta>5
The expression 4a - 5 - a + 2 can be simplified by combining like terms. Combining the terms with 'a', we get 4a - a = 3a. Combining the constants, we get -5 + 2 = -3. Therefore, the simplified expression is 3a - 3.

4a4 + 11a3 - 47a3 - 4a + 5 =4a4 - 36a3 - 4a + 5 =4a (a3 - 9a2 - 1) + 5
6a-3
