5a+5=6a-7
7a + 4 = 5a + 7 7a = 5a + 3 2a = 3 a = 3/2
5a = -5a + 5Add 5a to each side:10a = 5Divide each side by 10:a = 5/10 = 1/2
3a4 - 2a2 + 5a - 10 - 2a4 + 4a2 + 5a - 2 = a4 + 2a2 + 10a - 12 = a4 + (2a - 2)(a + 6)
3a x 2a =24
If: 5a-1+a = 11 Then: a = 2
A= 2
If: 2a+13 = 5a+1 Then: a = 4
6a + 5a = -11 11a = -11 a = -11/11 = -1
6a + 4 = 5a - 2 means that 6a - 5a = -2 - 4 which gives a = -6
1a (or just a for short).
2x+a=p 2x=p-a x=.5p-.5a
5a-20+2a = 6a-11 5a+2a-6a = 20-11 1a = 9 a = 9
5a + 2 = 7 subtract 2 from both sides: 5a = 5 divide both sides by 5: a = 1
-59
2a+5a+9a = 16a
4a + a = 25 add 4a and a 5a = 25 then divide 25 by 5 a = 5
