Step-by-step explanation:
<h3>Answer: x = 12</h3>
==============================================================
Work Shown:
Multiply both sides by the LCD 12 to clear out the fractions. Afterward, solve for x
x/2 - x/3 = x/4 - 1
12(x/2 - x/3) = 12(x/4 - 1)
12(x/2) + 12(-x/3) = 12(x/4) + 12(-1) ... distribute
6x - 4x = 3x - 12
2x = 3x - 12
2x-3x = 3x - 12-3x ... subtract 3x from both sides
-x = -12
x = 12
Answer:
x = -3, 6
Step-by-step explanation:
First, add 18 to both sides
x² - 3x - 18 = 0
+ 18 + 18
x² - 3x = 18
Add 9/4 to both sides because that is the square of half of -3
x² - 3x + 9/4 = 18 + 9/4
Multiply both sides by 4 to get rid of the fractions
(x² - 3x + 9/4 = 18 + 9/4)4
4x² - 12x + 9 = 72 + 9 = 81
Factor the left side of the equation
(2x - 3)² = 81
√(2x - 3)² = √81
Because of the square root, this will result in a positive number and a negative number
2x - 3 = 9
2x - 3 = -9
For both equations, add 3 to both sides then divide by 2
2x - 3 = 9
+ 3 +3
2x = 12
2x/2 = 12/2
x = 6
2x - 3 = -9
+ 3 + 3
2x = -6
x = -3

if you graph these equations, they will intersect at (4,1). They look very short because they are vertical and horizontal.
