Answer:
x-5<21
Step-by-step explanation:
X equals 6
How? Well first I multiplied 12 x 18 which is 216.
Then I subtracted 468 - 216 that equals 252.
Because I know that 2 x 6 equals a 12.....x had to be a 6.
So I multiplied 42 x 6 and it equaled 252.
So x is 6
Divide then multiply then do left to right
