The answer to the expression 25a^5 + 15a^4 - 35a^3 - 40a^3 + 10a divided by 5a is 5a^4 + 3a^3 - 7a^2 - 8a + 2.
5a- 2a = 3
6a + 4 = 5a - 2 means that 6a - 5a = -2 - 4 which gives a = -6
5a + 3 + (2a - 2) + a= 5a + 3 + 2a - 2 + a= 8a + 1
(5a+8) - (2a+4) =3a +4 To do this, simply subtract like terms. 5a-2a=3a and 8-4=4
-4(5a-3) = -20a + 12
7a + 4 = 5a + 7 7a = 5a + 3 2a = 3 a = 3/2
i dont understand what you mean by symbolic but ill just do an example 2a + 3 = 4 - 5a first collect like terms 2a +3 -3 = 4 -3 -5a 2a = 4-3 - 5a 2a + 5a = 1 - 5a + 5a 2a + 5a = 1 7a = 1 divide both sides by the coefficient of the unknwown(i.e. the number in front of the letter) 7a/7 = 1/7 a = 1/7
The answer to the expression 25a^5 + 15a^4 - 35a^3 - 40a^3 + 10a divided by 5a is 5a^4 + 3a^3 - 7a^2 - 8a + 2.
2a-8+4=45-5a 2a-4=45-5a 2a-4+4=45+4-5a 2a+5a=49-5a+5a 7a=49 / by 7 = A=7
5a + 3 = 7a - 1 add 1 to both sides 5a + 4 = 7a so 4 = 2a as 5a + 2a = 7a 4 = 2a = 2 x 2 so a = 2 Check: then 5a + 3 = 10 + 3 = 13 and 7a - 1 = 14 - 1 = 13
15a + 12 = 3(5a + 4)
3a2 - 16a + 5 = 3a2 - 15a - a + 5 = 3a(a -5) - 1(a -5) = (3a - 1)(a - 5)
Let the number be represented by 'a' a+(a+1)+(a+2)+(a+3)+(a+4)=465 a+a+1+a+2+a+3+a+4=465 a+a+a+a+a+1+2+3+4=465 5a+10=465 5a=465-10 5a=455 5a/5=455/5 a=91 So if a=91 a+1=92 a+2=93 a+3=94 a+4=95
5a- 2a = 3
6a + 4 = 5a - 2 means that 6a - 5a = -2 - 4 which gives a = -6
5a + 3 + (2a - 2) + a= 5a + 3 + 2a - 2 + a= 8a + 1
