Question

CAN SOMEONE HELP ME FIND THE LCD THAT WILL ISOLATE THE VARIABLE IN THE EQUATION , X/2+2/3=3/4 THANKS!

Answer 1

3=1?

Answer 2

X/2 +2/3 = 1/4

The LCD will need a 2, a 3, and another 2.

The first 2 comes from x/2.

The three comes from 2/3.

Where you see the 4 in 1/4, you might think 4 is a factor of the LCD because 4 = 2*2.

But, there is already one 2 from the first term. Only one more 2 is needed as a factor.

So, multiply 2 times 3 times 2 to get the LCD.

Answer 3

No that wasnt it.

Answer 4

ok see what u need to do is

Answer 5

multiplay all D

Answer 6

the least common multiple of 3 and 4 is 3 times 4 which is 12

Answer 7

@jenny1 >>No that wasnt it. Why do you say that?

Answer 8

\[\frac{x}{2}+\frac{2}{3}=\frac{3}{4}\]
\[12\left (\frac{x}{2}+\frac{2}{3}\right)=12\times \frac{3}{4}\]
\[6x+8=9\]solve for \(x\)
