5+3(1+4x-6)=6x+30
5+3(4x-5) = 6x+30
5+12x-15 = 6x+30
-10+12x = 6x+30
add 10 for both sides
12x= 6x +40
6x=40
x= 40/6

multiply and combine like terms within in the parenthesis
5 + 3 [ 1 + 2(2x - 3) ] = 6 (x + 5)
5 + 3 [ 1 + 4x - 6 ] = 6x + 30
5 + 3 [ 4x - 5 ] = 6x + 30
5 + 12x - 15 = 6x + 30
12 x -10 = 6x + 30 add 10 to both sides of the equation
12x -10 + 10 = 6x + 30 +10
12x = 6x + 40 subtract 6x from both sides of the equation
12x - 6x = 6x + 40 - 6x
6x = 40 divide both sides by 6
6x/6 = 40/6
x = 40/6
x = 6 4/6
x = 6 2/3 ANSWER
or x = 6.6666666
check answer by plugging in 6.66666 for x in the equaiton
5 + 3 [ 1 + 2( 2x - 3 ) ] = 6 ( x + 5 )
5 + 3 [ 1 + 2 ( 2 (6.6666667) - 3) ] = 6 ( (6.6666667) + 5)
5 + 3 [ 1 + 2(13.333333 - 3) ] = 6 (11.66666667)
5 + 3 [ 1 + 2(10.333333) ] = 70
5 + 3 [ 1 + 20.66666667 ] = 70
5 + 3 [ 21.66666667 ] = 70
5 + 65 = 70
70 = 70 CHECK

5 + 3[1 + 2(2x - 3)] = 6(x + 5)
5 + 3[1 + 4x - 6] = 6x + 30
5 + 3 + 12x - 18 = 6x + 30
-10 + 6x = 30
6x = 40
x = 40/6

5 + 3(1 + 4x - 6) = 6x + 30
5 + 12x - 15 = 6x + 30
6x = 40
x = 40 / 6
x = 20 / 3

5+3[1+2(2x-3)]=6(x+5)
5+3[1+4x-6]=6x+30
5+3+12x-18=6x+30
10-12x=6x+30
-6x+10-12x=30
-6x-12x=20
-18x=20
x= -20/18 ---> -10/9

properly if a million+2i is one answer then a million-2i could desire to be yet another hence. (x-a million+2i)(x-a million-2i) = x^2-2x+5 could desire to pass into your polynomial. because it seems it does and supplies x^2 - 4x + a million. making use of the Pythagorean theorem to come to a decision the different strategies you get 2+?3 and 2-?3 through fact the different 2 strategies.
