Answer:
x = 2 and y = 1
Step-by-step explanation:
A) 5x+y=11
B) x - y = 1.
(Solving by substitution)
B) x - 1 = y
A) 5x + (x -1) = 11. 6x-1=11. 6x = 11+1
6x = 12
x = 12/2. x = 2
B. 2 - 1 = y. y = 1
The answer is A because 75 + 15 is 90
Answer:
-24
Step-by-step explanation:
Start by distributing the exponent to each of the terms in
. This will become
, and
. Now, the expression is:
.
We can now simplify the bottom to read:
because when multiplying variables raised to an exponent, we add the exponents. The expression now looks like:

The 2/8 simplifies to 1/4:

Now, we have two u terms on the top and bottom. When dividing variables raised to an exponent, we subtract the exponents. However, since 3-5=-2, the term will be on the bottom to avoid the negative exponent. The final answer is:

Hope this makes sense!!
