Well.
Multiply both sides by 'c'.
After that you should have something like ac=b-4
then you add 4, to get this result
4+ac=b.
n=-4/3
x=-1 ^ how do you know?
4/9 minus 3/4 equals -11/36
minus 5
find the common multiple of 4 and 480 then minus 4. Answer is 1 over 3 and N squared. Your welcome i am your saviour.
16
2/5 minus 4/9 equals -2/45
first you add 2 to the 8. the 2 crosses out itself so now you have b over 4 equals 10. then you multiply the 4 to the ten and the 4 the 4 crosses out itself and you end up with b= 40
Question 3C: Four minus seven equals negative two.
A = 12 and 4/5
6 - 3x = 4 - 2x 6 = x + 4 x = 2 Check it. 6 - 6 = 4 - 4 It checks.
...7 over 36?
