b= 4

If b = -1.5 then -4.5 -2 = -10.5 + 4, which is true.

3b+4 = b+12 3b-b = 12-4 2b = 8 b = 4

2a + 3b

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

It does not.

12 + 4 = 16

If the x=4, then its equivelent to 12 + 4, which equals 16.

144 9+7 = 16 and 9*16 = 144

16 + 9 - 4 = 21
