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.
All of these involve simple substitution. Just replace the variable with the actual value.
8z + 3 >>> 8(8) + 3 = 64 + 3 = 67
3(7+ x^2) >>> 3(7 + 2^2) = 3(7 + 4) = 3(11)=33
s - 5t + s^2 >>> 4 - 5(-1) + 4^2 = 4 + 5 + 16
Get the trend? I am not sure I get that last one, is it:
x - y*3^2?
