1. Which would be a more helpful for solving the system: adding the two equations or subtracting one from the other? Explain your reasoning.
2. Solve the system without graphing. Show your reasoning.

2x+1/2y=7
6x-1/2y=5

1) Subtracting one from the other

2) x = 0.375 and y = 0.125

Step-by-step explanation:

Equation 1 :

Equation 2:

To solve these equations by the Elimination method we multiply equation 1 with 6 and multiply equation 2 with 2 so now,

Now for the second equation:

Now subtracting equation 2 from equation 1

now insert this value of y into any equation

lets insert it into equation 1

i dont know sorry

step-by-step explanation:
