Which statement correctly explains how andre could find the solution to the following system of linear equations using elimination?

multiply the first equation by –7 and the second equation by 8, and then subtract.
multiply the first equation by -7 and the second equation by 8, and then add.
multiply the first equation by 2 and the second equation by 9, and then add.
multiply the first equation by –2 and the second equation by 9, and then subtract.

The correct answer is B.

Step-by-step explanation:

Multiply the first equation by -7, and the second equation by 8, and then add.

What you're trying to do is cancel them out so they have to opposite signs in order for them to cancel out. You can't do that if the signs are the same, which is what option A suggests doing. B is the correct answer.

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
