2(3-10x)+4 (5x+2)=-6
6-20x+20x+8=-6
14= -6
This is not possible. Thus, the equation above does not have any solution. There is value of x that can satisfy the equation.

2(3-10x)+4 (5x+2)=-6 both side divided by 2
(3-10x)+2 (5x+2)=-3
3-10x+10x+4=-3
3- 4 = -3 wrong question

2(3-10x)+4(5x+2)= -6
6-20x + 20x+8=-6
6+8 = -6
14 does not equal -6

2(3-10x)+4(5x+2)=-6
multiply through with the two and the four - 6-20x+20x+8=-6
combine like terms - 14+40x=-6
isolate the variable - 40x=-20
solve for x - x=-1/2

square
36 = 4(3-10x)^2 + 16(5x+2)^2 +16(3-10x)(5x+2)
4(100x^2 -60x + 9) => 400x^2 -240x +36
16(25x^2 -20x + 4) => 400x^2 -320x +64
16(-50x^2 -5x + 6) => -800x^2 - 80x + 96
36 = -640x + 196
36 - 196 = -640x
x = 1/4

2(3-10x)+4 (5x+2)=-6
6-20x+20x+8=-6
-20x+20x=-6-6-8
0=-20
there is no solution to this problem.

no seriously 14
6-20x+20x+8 got 2 look at the sign in front of the #, -20x+20x cancels out = 0
6+8=14 14+0=14
