Answer:
13 or -1
Step-by-step explanation: 3/4(x+2)=x/(x+2)
3x+6/4=x/(x+2) we cross multiply
4x+(3x+6)(x+2)
4x=3x²+6x+6x+12
4x²=3x²+12x+12
4x²-3x²-12x-12=0
x²-12x-12=0
-b+or -√b²-4x/2x
12=or-√12²-4×1x-12/2×1
12+or-√144-48/2
12=or-√192/2
12+14/2 or 12-14/2
13or -2/2
13 or -1
Answer:
x = 3/4
Step-by-step explanation:
The lowest common denominator is 4(x + 2) so we multiply each side by this:
3 = 4x
x = 3/4.
