∙ 2010-04-15 15:45:58a = 11 and b = 5.
(3b - 4)(3b - 4)
3b -2 =7 b+4
-13
3b
3b+4 = b+12 3b-b = 12-4 2b = 8 b = 4
b= 4
If b = -1.5 then -4.5 -2 = -10.5 + 4, which is true.
Write down both equations (I'll label them (1) and (2)):(1) a = 3b - 4(2) a + b = 16Pass b to the left side of the equation (1):(1) a - 3b = -4(2) a + b = 16Multiply (1) by -1:(1) -a + 3b = 4(2) a + b = 16Add down both equations:-a + 3b + a + b = 4 + 164b = 20b = 5Replace b in (2):a + 5 = 16a = 11
