Which of these strategies would eliminate a variable in the system of equations? ​8x+8y=2 8x+5y=1 ​ Add the equations. (Choice B
harkovskaia [24]

Answer:

B. Subtract the bottom equation from the top equation.

Step-by-step explanation:

When looking at the two equations:

8x + 8y = 2

8x + 5y = 1

We can easily get rid of the x variable by subtracting the two equations from each other since the terms are equivalent. This would allow us to solve for the y value, which we could plug into the an equation to solve for the x value.

I need help with my homework please answer this correctly
Bogdan [553]

2 numbers can be represented by the variables x and y.

Set up a system of equations:

x + y = 33

x - y = 1

The two numbers added together will result in a sum of 33. However, one number subtracted from another will result in a difference of 1.

In both systems of equations, there are inverses of variable y. Therefore, we can combine the systems of equations by adding them together:

(x + x) + (y - y) = (33 + 1)

2x = 34

Divide both sides by 2 to get x by itself:

x = 17

One of the numbers will be 17.

Plug the value into one of the equations:

17 - y = 1

Add y to both sides:

17 = y + 1

Subtract both sides by 1 to get y by itself:

y = 16

The two numbers that sum up to 33, with a difference of 1 between them, will be 16 and 17.
