Question

Solve for x using common denominators. 3/4(x + 2)=x/(x+2)

Answer 1

x = 3/4

Explanation:

The lowest common denominator is 4(x + 2) so we multiply each side by this:

3 = 4x

x = 3/4.

Answer 2

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
