Which ordered pair is the solution to the system of equations? x= 1/2y+5 2x+3y= −14 a. ( 2,-6) b. (8,9) c.(18,14) , -12) you in

You can use substitution or elimination method to solve.  I used substitution.

2(1/2y + 5) + 3y = -14

y + 10 + 3y = -14

4y + 10 = -14

4y = -24

y = -6

x = 1/2y + 5  = 1/2(-6) + 5   = -3 + 5  = 2

x = 2, y = -6

A

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

answer: about 22.67
