Subtract 4 from both sides of the equation
you will end up with 2/7x=4
next multiply 7x by both sides
you will end up with 2=28x
next divide 28 from both sides
you will end up with x=1/14 in
fraction form. Hope this helps.

4+2/7x=8
minus 4 from both sides
2/7x=4

now there are 2 paths possible
1. 2/(7x)=4, if so, go to AAAAAA
2. (2/7)x=4, if so, go to BBBBBB


AAAA
2/(7x)=4
times both sides by 7x
2=28x
divide both sides by 28
1/14=x

BBBBBBB
(2/7)x=4
times both sides by 7/2
x=28/2
x=14


x=1/14 or 14 depending on how the fraction is
1/14 if 2/(7x), 14 if (2/7)x

Estimate 10/12 − 3/8 using benchmark values. Your equation must show the estimate for each fraction and the final estimate for t
Maksim231197 [3]

Answer: \frac{11}{24}

Step-by-step explanation:

Give expression is,

\frac{10}{12}-\frac{3}{8}

Since L.C.M ( 12, 8 ) = 24

=\frac{10\times 2}{12\times 2}-\frac{3\times 3}{8\times 3}

=\frac{20}{24}-\frac{9}{24}

=\frac{20-9}{24}

=\frac{11}{24}

\text{Hence, }\frac{10}{12}-\frac{3}{8}=\frac{11}{24}
