Find x if the meanof 1,3,6,8,x is 6

x=12

Step-by-step explanation:

(1+3+6+8+x)/5=6

1+3+6+8+x=30

18+x=30

x=12

12.

Step-by-step explanation:

There are 5 numbers so the sum, if the mean is 6, is 30.

1 + 3 + 6 + 8 + x = 30

18 + x = 30

x = 30 - 18 = 12.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
