What is 5x-4 2x-8?
5x-4=8+2x 5x-2x=4+8 3x=12 x=12/3 x=4
Factor 2x2 - 5x-12?
2xx-5x-12 2*-12=-24 -24=-8*3 -8+3=-5 2xx-8x+3x-12 2x(x-4)+3(x-4) (2x+3)(x-4)
2x-4 equals 12 what is the value of x?
2x - 4 = 12Add 4 to each side:2x = 16Divide each side by 2:x = 8
5x-8 equals -2x plus 6?
5x-8= -2x+6(+8 = +8)5x=-2x+14(+2x = +2x)7x=14x=14
6x - 8 plus 2x - 5 equals 7 - 2x?
6x - 8 + 2x - 5 = 7 - 2x ?
What is 8 2x?
5x-4=8+2x 5x-2x=4+8 3x=12 x=12/3 x=4
What is the answer to 2x-4 equals 6x plus 8?
2x-4=6x+8-8= -82x-12= 6x-2x= -2x-12= 4x/4=/4-3=x
What is 5x-4 2x-8?
5x-4=8+2x 5x-2x=4+8 3x=12 x=12/3 x=4
What is 4 2x?
5x-4=8+2x 5x-2x=4+8 3x=12 x=12/3 x=4
What is the soultion of y -8 and y -2x-12?
If you mean: y = -8 and y = -2x-12 then the solution is x = -2 and y = -8
What is the solution set of 2x - 3 - 8 equals 1?
2x - 3 - 8 = 1. 2x - 11 = 1. 2x = 12.x = 6!
What is 2x-4 or equal to 8?
2x - 4 = 82x = 8 + 4 = 12x = 12/2 = 6
- 4x - 8 equals - 2x plus 12?
-4x - 8 = -2x + 12Add 4x to each side:-8 = 2x + 12Subtract 12 from each side:-20 = 2xDivide each side by 2:-10 = x
4 times the sum of a number and 5 is 8 more than twice the number?
4(x + 5) = 2x + 8 4x + 20 = 2x + 8 2x = -12 x = -6
2x plus 8 equals 3x-4?
2x + 8 = 3x - 4 Subtract 2x from both sides: 8 = x - 4 Add 4 to both sides: 12 = x
What is the answer to 2x plus 8 over 4 equals 2x - 8 over 3?
(2x + 8)/4 = (2x - 8)/3 Multiply both sides by 12 to get rid of the fractions: 3*(2x + 8) = 4*(2x - 8) Simplify: 6x + 24 = 8x - 32 Subtract 6x from both sides: 24 = 2x - 32 Add 32 to both sides: 56 = 2x or 2x = 56 Divide both sides by 2: x = 28
2x plus 4y equals 12 solve for y?
2x + 4y = 12 ie 4y = 12 - 2x so y = 3 - x/2 Test: take x as 8 so y = -1: 2 x 8 + 4 x -1 does indeed = 12.
