well if you know distributive property.....
4(x-3) = (4)(x) + (4)(3) = 4x-12
and [tex]4x-12 =4x-3\\4x-4x-12= 4x-4x-3\\-12 \neq -3[/tex] False not equivalent
[tex](2n)^{3} = 2^3*n^3=8n^3\\ 8n^3 = 8n^3[/tex] These expressions are equivalent
Last one....[tex]\frac{6x-3}{3} = \frac{3(3x-1)}{3} = 3x-1\\ 3x-1\neq 2x[/tex] False not equivalent
