-4x + 8 = -4 -4x + 8 - 8 = -4 -8 -4x = -12 -4x/-4 = -12/-4 x = 3
collect like terms and you get 4x + 5x + 8 - 3 ie 9x +5
20x2 - 27x -8 20 * -8 is -160, and -32 and 5 add to -27 20x2 - 32x + 5x - 8 4x(5x-8) + 1(5x-8) (4x + 1)(5x-8)
-3x-8+4x=17(-3x+4x)-8=17 ;combine like terms(x)-8=17 ;add 8 to both sidesx=25
4x - 7 = -15 4x = -8 x = -2
In order to answer the question, you need to isolate your terms, that is getting "x" alone on one side of the equation and the integer values alone on the other. 5x - 6 = 4x + 8 Start by adding 6 to both sides of the equation. 5x - 6 + 6 = 4x + 8 + 6 5x = 4x + 14 Then, subtract 4x from both sides. 5x - 4x = 4x - 4x + 14 x = 14 There's your answer!
If you mean: 4x-6+5x = 13x-8 then it works out that x = 1/2 or 0.5
This one looks like No Solution. This is how I read it: 5x = 8 = 98-4x. If 5x = 8, then x = 8/5 = 1 3/5 (or 1.6), substitute into 98 - 4x --> 98 - 4(1.6) = 91.6, which does not equal 8, as it should from the equation.
9x + 8 = 4x + 23Subtract 8 from both sides9x = 4x + 15Subtract 4x from both sides5x = 15Divide both sides by 5x = 3
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
-4x + 8 = -4 -4x + 8 - 8 = -4 -8 -4x = -12 -4x/-4 = -12/-4 x = 3
-3
x = -8
2x + 3 + 3x = x + 11 5x + 3 = x + 11 4x + 3 = 11 4x = 8 x = (8/4) x = 2
3X - 23 + 4X + 6 = 5X + 8combining like terms, 7X - 17 = 5X + 8subtracting 5X and adding 17 to each side, 7X - 5X = 8 + 17Then, 2X = 25X = 12.5
8+4x
We are given: 4x - 8 = 12Add 8 to both sides: 4x = 20Divide by four on both sides: x = 5
