Question

Solve.3 over x minus 1 + 2 over x = 4
A. {0.25, 2}
B. {1/2, 2}
C. {1/2, 1}
D. {.25, 1}

Answer 1

3/x-1+2/x=4

Answer 2

if 1 is also under 3 together with x, then multiply both sides by the LCM first which is x(x-1)

so 3x + 2(x-1) = 4(x(x-1))

3x + 2x -2 = 4x^2 - 4x
-4x^2 + 4x + 3x +2x = 2
-4x^2 + 9x = 2
x(-2x + 9) = 2
x = -2; x = 3.5

Answer 3

oh okay i was confused about the lcm thank you
