Whats equivalent to 14(8−6x+12)

iren2701 [21]

We can use the distributive property to set up an expression that is equal to this problem.

14 times 8 is 112
14 times -6 is -84x
14 times 12 is 168
(If you don't know the distributive property ask and I can explain it)

We can combine that together to get:

112 +168 -84x
Or, condense it further:

280-84x is equivalent to 14(8-6x+12)
