Which of these strategies would eliminate a variable in the system of equations? 8x+8y=2 8x+5y=1 Add the equations. (Choice B
) B Subtract the bottom equation from the top equation. (Choice C) C Multiply the top equation by 1/2,then subtract the bottom equation from the top equation.
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.
