If: 5a-1+a = 11 Then: a = 2
A= 2
If: 2a+13 = 5a+1 Then: a = 4
5a = -5a + 5Add 5a to each side:10a = 5Divide each side by 10:a = 5/10 = 1/2
6a + 5a = -11 11a = -11 a = -11/11 = -1
5a + 2 = 7 subtract 2 from both sides: 5a = 5 divide both sides by 5: a = 1
6a + 5a = -11 Combining like terms: 11a = -11 Dividing by 11: a = -1
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
5a + 3 + (2a - 2) + a= 5a + 3 + 2a - 2 + a= 8a + 1
5a - 1 = a - 7 4a = -6 a = -1.5
Begin by writing it down:-5a + 6 = 56Subtract 6 from each side:-5a = 50Divide each side by 5:-a = 10Multiply each side by -1 :a = -10
