-2x^4+16 +2x^4+9-3x^5=-3x^5+25. There is no "answer" because there is no equation.
2x + 7 + 2x = 23 4x + 7 = 23 4x = 16 x = 16/4 x = 4
It is; (2x+4)^2.
2(4x+8) 4(2x+4) 8(x+2)
you add 4 to both sides (2x-4 and 16) to cancel out the 4 and get 2x=20. then you divide both sides by 2.
7-3(4-2x)-10x 4(4)-2x)-10x 16-8x-10 16-18x
2x+4 = -16 2x = -16-4 2x = -20 x = -10
2x + 4 = 16 2x = 16 - 4 2x = 12 x = 12/2 x = 6
2x + 7 + 2x = 23 4x + 7 = 23 4x = 16 x = 16/4 x = 4
The value of X in the equation 2x plus 36 = 4 is -16.
(4 + 2x) - (-2x + 1) = 13 + 6 4 + 2x + 2x -1 = 19 4x +3 = 19 4x = 19 - 3 4x = 16 therefore x = 16/4 x = 4
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
= 2x + 4

x=3
2x + 4 = 362x = 36 - 42x = 32x = 32/2X = 16
4
x= 2 because 2x+4=16 4x2=8 8+2 or 8x2=16
