The answer is 1/6 x (25/3m^2n^2-1)
1+1=2 because it is simple maths ok
Solution:
1) Subtract 7 from both sides
y-7=4x
2) Divide both sides by 4
\frac{y-7}{4}=x
3) Switch sides
x=\frac{y-7}{4}
Done!
The answer is 3/8. You have to change 3/4 to 6/8 and divide it by 2. 6÷2=3 so the answer is 3/8
a. If you multiply both sides of 2/3 by 3, you get 6/9. None of the others are correct because they are all 0/6 etc, which is equal to 0.
