4x - 8 = 5x
1) Add 8 to both sides.
4x - 8 (+ 8) = 5x (+ 8)
Becomes 4x = 5x + 8
2) Subtrate 5x from both sides.
4x (- 5x) = 8
Becomes -1x = 8
Reduced to -x = 8
3) Multiply both sides by -1.
Becomes x = -8

4x - 7 = -15 4x = -8 x = -2
Solve for x 5x-6 equals 4x plus 8?
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!
How do you solve 4x-6 plus 5x 13x-8?
If you mean: 4x-6+5x = 13x-8 then it works out that x = 1/2 or 0.5
What is 5x equals 8 equals 98-4x?
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 plus 8 equals 4x plus 23 x equals?
9x + 8 = 4x + 23Subtract 8 from both sides9x = 4x + 15Subtract 4x from both sides5x = 15Divide both sides by 5x = 3
How do you solve y equals 4x-8 and y equals 2x plus 10?
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)
How do you solve -4x plus 8 equals -4?
-4x + 8 = -4 -4x + 8 - 8 = -4 -8 -4x = -12 -4x/-4 = -12/-4 x = 3
Y equals -4x-1 in standard form?
-3
How do you solve 16 plus 5x equals 3x?
x = -8
How do you solve 2x plus 3 plus 3x equals x plus 11?
2x + 3 + 3x = x + 11 5x + 3 = x + 11 4x + 3 = 11 4x = 8 x = (8/4) x = 2
3X-23 plus 4X plus 6 equals 5X plus 8?
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
Solve 8 plus x equals 4 in simplest form?
8+4x
How do you solve 4x-8 equals 12?
We are given: 4x - 8 = 12Add 8 to both sides: 4x = 20Divide by four on both sides: x = 5
