Answer:
x = Approximately 4.92. (Tech: 4.923076923076923)
Explanation:
To solve for x in the equation,
x - 1/4(12 - x) = x + 3(4 - x) - 2x
Expand the terms on the right side:
x - 1/4(12 - x) = x + 12 - 3x - 2x
Combine like terms:
x - 1/4(12 - x) = -3x + 12
Isolate x on one side of the equation:
1/4(12 - x) + 3x = 12 + x
Combine like terms:
1/4(12 - x) + 3x = 13
Distribute 3x:
1/4(12 - x) + 3x = 13
3x = 13 - 1/4(12 - x)
Multiply both sides by 4:
12x = 52 - (12 - x)
Combine like terms:
13x = 64
Finally, divide both sides by 13:
x = 4.923076923076923
So the value of x is approximately 4.92.
