If 4x minus 7 equals 2x plus 5 what is x?
4x - 7 = 2x + 5 2x - 7 = 5 2x = 12 x = 6.
What is 4x minus 7 equals 5 plus 7x?
4x - 7 = 5 + 7x x = -4
X plus 5 plus 3x - 7 plus 9x plus 3 - 4x?
x + 5 + 3x - 7 + 9x + 3 - 4x Switch the like numbers closer to make the equation easier. x + 3x + 9x - 4x + 5 - 7 + 3 However this is an unsolvable as it isn't an equation. An equation needs an equals sign, for example: x + 3x + 9x - 4x + 5 - 7 + 3 = 0, or x + 3x + 9x - 4x + 5 - 7 + 3 = 10 If it is the former then the answer is 9x = -1 Thus x = -1/9

What is the solution to 4x squared minus x minus 5 equals 0?
4x2 - x - 5 = 0 4x2 + 4x - 5x - 5 = 0 4x(x + 1) - 5(x + 1) = 0 (4x - 5)(x + 1) = 0 4x - 5 = 0 or x + 1 = 0 4x = 5 or x = -1 x = 5/4 o x = -1
What is the answer to 4x-5 equals 7?
4x-5=7 4x=12 x=3
What is 4x - 7 5?
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
How do you solve 5 plus 4x - 7 equals 4x plus 3 - 1x?
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
What is the answer to 5 plus 4x-7 equals 4x plus 3-x?
5 + 4x - 7 = 4x + 3 - x (eliminate alike terms in both sides)5 - 7 = 3 - x (leave the variable alone by itself)5 - 7 - 3 = 3 - 3 - x-5 = -x (multiply both sides by -1)5 = x
What is 10x-7 equals 4x plus 5?
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
How do you simplify y equals 2x-5 and 4x-y equals 7?
y = 2x-5 4x-y = 7 => y = 4x-7 2x-5 = 4x-7 2x-4x = 5-7 -2x = -2 x = 1 Therefore by substituting: x = 1 and y = -3
If 4x minus 7 equals 2x plus 5 what is x?
4x - 7 = 2x + 5 2x - 7 = 5 2x = 12 x = 6.
4x - 7 equals 5x - 2 what does x equals?
4x-7=5x-2 x=-5
What is 4x minus 7 equals 5 plus 7x?
4x - 7 = 5 + 7x x = -4
What is 4x plus 5 equals -7?
Well, your equation probably looks like this: 4x + 5 = -7 So you would follow these steps to get x by itself. 4x + 5 = -7 Subract 5 from both sides and you get 4x = -12 4x = -12 Divide both sides by 4 to get x by itself x = -3
What is the answer to 5-4x equals 12-2x?
5-4x=12-2x isolate your x's on one side 5=12-2x+4x 5-12=-2x+4x simplify -7=2x divide by 2 x=-7/2, or x=-3.5
2x plus 5 equals 7-4x?
2x + 5 = 7 - 4x ie 2x + 4x = 7 - 5 ie 6x = 2 x = one third.
