Question

x-3 3x + 4
_____ - ________ = 3
2 2 x-3 3x + 4
_____ - ________ = 3
2 2 @Mathematics

Answer 1

Multiply everything by 2. x-3-3x-4=6
Group everything and solve for x.

Answer 2

Times everything by two (the numerator and denominator). The answer is as follows:
\[\left( 2x-6-6x+8 \right)\div \left( 4 \right)=3\]
Simplify:
\[\left( -4x+2 \right)\div \left( 4 \right)=3\]
Bring the 4 over to the other side of the equals sign, turning it into a times:
\[-4x+2=12\]
Finally:
\[-4x=12-2\]
\[-4x=10\]
\[x=10\div\left( -4 \right)\]
\[x=-2.5\]
Hope this helps!
