What is X if 2x 4 36?
What is X if 2x + 4 = 36 What is X ? 2x + 4 = 36
2x plus x plus 4 plus 2x equals x plus 20?
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
3X-4 all over 1- 2X-4?
If 3X - 4 ------ = 0 1-2X-4 So 3X - 4 ----- = 0 [ x (2X-3) ] 2X-3 3X-4 = 2X-3 [ -2X ] X - 4 = -3 [ +4 ] X= 1
2x - 6 equals 4 then what is the value of x?
2x - 6 = 4 2x = 4 + 6 = 10 x = 10/2 = 5 ∴ x = 5
What are the zeros in the function of 2X squared plus 3X -20 equals zero?
2x^2 + 3x - 20 = 0 is 2x^2 + 8x - 5x -20 = 0 is 2x(x + 4) -5(x + 4) = 0 is (2x - 5)(x +4) = 0 Hence 2x -5 = 0 which gives x = 2.5 or x + 4 = 0 which gives x = -4
What is X if 2x 4 36?
What is X if 2x + 4 = 36 What is X ? 2x + 4 = 36
2x - 6 4?
2x-6=4 6+4=2x 10=2x 10/2=x 5=x x=5
2x plus x plus 4 plus 2x equals x plus 20?
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
If 2x plus 4 equals 16 then x is what?
2x + 4 = 16 2x = 16 - 4 2x = 12 x = 12/2 x = 6
4 equals x plus 2?
4 + x = 2x --> 4 = 2x - x --> 4 = x: x = 4
What is the answer to 4-2x equals 10?
4 - 2x = 10 -2x = 10-4 -2x = 6 -x = 3 x = -3
What does 4x-2x plus 4 equals x plus 10 equal?
If 4x - 2x + 4 = 10, the solution is 2x + 4 = 10 and x = 3.
3X-4 all over 1- 2X-4?
If 3X - 4 ------ = 0 1-2X-4 So 3X - 4 ----- = 0 [ x (2X-3) ] 2X-3 3X-4 = 2X-3 [ -2X ] X - 4 = -3 [ +4 ] X= 1
2x plus 4 equals -16?
2x+4 = -16 2x = -16-4 2x = -20 x = -10
How do you factor 2x cubed - 32x?
2x(x - 4)(x + 4)
How do you factor 4x squared - 16?
(2x + 4)(2x - 4) to check your answer, use the FOIL method (first, outside, inside, last) F.... 2x x 2x = 4x^2 0.... 2x x -4 = -8x I..... 2x x 4 = 8x L.... 4 x -4 = -16 so 4x^2 - 16 = (2x + 4)(2x - 4)
How do you solve the equation 4 plus x equals 2x?
4+ X equals 2X. Subtract X from both sides. Four equals X
