PLEASE HELP ME... I AM BEHIND ON MATH HOMEWORK AND I REALLY NEED TO CATCH UP SO I DON'T GET MY PHONE TAKEN AWAY Solve the following system of equations. SHOWING ALL STEPS.

LaTeX: 5x-4y=-2

LaTeX: 2x+4y=16


Use the LaTeX: \sqrt{x} button to show your math and steps. Also, a table might help you organize your work.

Sorry Dont know this.

Step-by-step explanation:

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!
