Answer:
The answer to your question is letter D
Step-by-step explanation:
Rational equation

Simplify

Cancel the denominators and expand
3x² + 1 + x² - x = 4x - 4 + 4
Simplify
4x² - x + 1 - 4x = 0
4x² - 5x + 1 = 0
Factor
4x² - 4x - 1x + 1 = 0
4x(x - 1) - 1(x - 1) = 0
(4x - 1)(x - 1) = 0
x₁ = 1/4 x₂ = 1
5x-5=4x+10
x=15
75-5=70
180-70=110
6y-4=110
6y=114
y=19
