Question

Can someone please help me?!!!!

Answer 1

Firstly let’s assume she is correct and use an equal sign:
1/2(12x + 24) = 3(2x + 4)

Now simplify both sides:
1/2 • 12x = 6x
1/2 • 24 = 12
6x + 12

3 • 2x = 6x
3 • 4 = 12
6x + 12

And:
6x + 12 = 6x + 12
Therefore they are equivalent, she is correct.
