Solve the following equation when x=2 and y=4
3x+2y+4=

18

Step-by-step explanation:

plug in

=2y+10

Step-by-step explanation:

You just have to plug them into the equation which turns it into 3(2)+2y+4)= then simplify it which is

(3)(2)+2y+4

=6+2y+4

then combine like terms

=6+2y+4

=(2y)+(6+4)

=2y+10

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)
