Solve 9x + 5y + 3z = 4 6x + 2y + 4z = 2 -3x + 3y – 7z = 2 (-1, 2, 1) (1, -1, 0) (4, 2, 2) (1, 2, -5)

$12. that is my answer.

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!
