Here is a system of linear equations: 2x + 1/2y= 7
6x - 1 / 2y=5
Which would be a more helpful for solving the system: adding the two equations or
subtracting one from the other? Explain your reasoning.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

16
