Is (3, 6) a solution to this system
of equations?

2x+7y=48
5x+3y=51

No, because the solution in this equation is (213/29 , 138/29)

Step-by-step explanation:

2x + 7y = 48 (Multiply this by 5)

5x + 3y = 51  (Multiply this by -2)

10x + 35y = 240

-10x - 6y = -102

29y = 138

y = 138/29

2x + 7y = 48

2x + 7(138/29) = 48

2x + 966/29 = 48

2x = 426/29

x = 213/29

(213/29 , 138/29)

is there answer choices?

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!
