Help me please with this

(3,2)

Step-by-step explanation:

2x+5y=16

3x-5y=-1

add

5x= 15

x=3

plug back in

2(3)+5y=16

6+5y=16

5y=10

y=2

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
