2x+4 = -16 2x = -16-4 2x = -20 x = -10

2x + 4 = 16 2x = 16 - 4 2x = 12 x = 12/2 x = 6

The value of X in the equation 2x plus 36 = 4 is -16.

2x + 7 + 2x = 23 4x + 7 = 23 4x = 16 x = 16/4 x = 4

(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 + 4

2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4

2x + 4 = 362x = 36 - 42x = 32x = 32/2X = 16

2x2=4x4=16

It is; (2x+4)^2.

x= 2 because 2x+4=16 4x2=8 8+2 or 8x2=16

10x^3 plus 14x^2-4x+16

8x-4

It is an algebraic expression that can be simplified to: 23x-16

2(x + 4)(x + 2)

2x + 4y = 16 <=> 2x + 4y - 16 = 0 2x - 4y = 0 2x - 4y = 2x + 4y - 16 -8y = -16 y = 2 Substituting the known value for y in either of the original equations enables x to be determined. 2x + (4*2) = 16 : 2x = 16 - 8 : x2x = 8 : x = 4 2x - (4*2) = 0 : 2x - 8 = 0 : 2x = 8 : x = 4. The ordered pair satisfying both equations is (4,2)

2x+4+7x-4 is the same as 9x

x equals 4

2x + 4 = 162x + 4 - 4 = 16 - 42x = 122x/2 = 12/2x = 6
