-5a + b = 2 AND -a - 5b = 0 -5a + b = 2 b = 2 + 5a *using above -a - 5b = 0 -a - 5(2 + 5a) = 0 -a - 10 - 25a = 0 -26a = 10 a = 10/-26 *using 'a' value 5a + b = 2 5(10/-26) + b = 2 -25/13 -2 = -b b = 51/13 Therefore a = 10/-26 b = 51/13
the value that makes this ewuation true 5a=a is 2a
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)

2a-5=-3a5a-5=05a=5a=0
If: -5a = 300 Then: a = -60
The square root of both 0 and 1 equals the square of 0 and 1
5a+5=6a-7
(5a).7 = -23 7(5a) = -23 35a = -23 a = -23/35 a= -0.657 (3 d.p.)
4a^2 - 5a^2 = -a^2
Divide 5a and 180 by 5. a = 36
