A+5=-5a+5 A=-5a+5-5 (bring one of the 5 over)(not necessary) A=-5a (if big and small letters are the same, A=a=0; if not, when A=35,a=-7)
-13
2a+5a+9a = 16a
5a + 2 = 7 subtract 2 from both sides: 5a = 5 divide both sides by 5: a = 1

5a+5=6a-7
A+5=-5a+5 A=-5a+5-5 (bring one of the 5 over)(not necessary) A=-5a (if big and small letters are the same, A=a=0; if not, when A=35,a=-7)
5a = -5a + 5Add 5a to each side:10a = 5Divide each side by 10:a = 5/10 = 1/2
a is equal to 4

If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
5(9)+2= 47
5a(a(a-5)+3)
2a+5a+9a = 16a
5a + 2 = 7 subtract 2 from both sides: 5a = 5 divide both sides by 5: a = 1

a + 3a + 5a = 180 9a =180 a = 20
