Answer 7

try using PEMDAS
to simplify 4 • 7 – 4 • 10 what would you get? :)

Answer 8

-12

Answer 9

right :)
then what do you get from distributing out 4(x-10) ?

Answer 10

wouldn't -12 be x?

Answer 11

not quite
because you have 4(x-10) on the other side...
could you distribute out 4(x-10) ? :)

Answer 12

7?

Answer 13

*sigh* yeah x = 7

Answer 14

Answer 15

my brain gets confused when people just guess the answers when I'm trying to get them to do something else :P

Answer 16

i didn't guess though i worked it out i put the numbers where x was to see if i got -12 so if i put 4(7-10) i get -12 so it was 7
