sry if im wrong...
Explanation:
2(3 + 4x) = 8x + 6
rerange terms-
2(3+4x)= 8x+6
2(4x+3)= 8x+6
distribute-
2(4x+3)= 8x+6
8x+6=8x+6
subtract 6 from both sides of the equation-
8x=8x
subtract 8x from both sides of the equation-
8x=8x
8x-8x=8x-8x
simplify-
0=0
result-
0=0
the input is an identity: it is true for all values
