Answer:
u = 1
Step-by-step explanation:
First, we can use inverse operations to help.
27 + 9u = 36
Next, we can start replacing u with numbers to find which number fits in u.
27 + 9(1) = 36
27 + 9(2) ≠ 36
27 + 9(3) ≠ 36
Now, we know that u = 1
Remember
a/b times c/d=(ac)/(bd)
basically
x/y times c/d such that x times c=8 and y times d=15
exampes
8/1 times 1/15
2/1 times 4/15
4/1 times 2/15
8/3 times 1/5
2/3 times 4/5
4/3 times 2/5
8/5 times 1/3
2/5 times 4/3
4/5 times 2/3
