\frac{10}{7}=a+\frac{1}{\frac{bc}{c}+\frac{1}{c}}
To add or subtract expressions, expand them to make their denominators the same. Multiply b times \frac{c}{c}.
\frac{10}{7}=a+\frac{1}{\frac{bc+1}{c}}
Since \frac{bc}{c} and \frac{1}{c} have the same denominator, add them by adding their numerators.
\frac{10}{7}=a+\frac{c}{bc+1}
Divide 1 by \frac{bc+1}{c} by multiplying 1 by the reciprocal of \frac{bc+1}{c}.
\frac{10}{7}=\frac{a\left(bc+1\right)}{bc+1}+\frac{c}{bc+1}
To add or subtract expressions, expand them to make their denominators the same. Multiply a times \frac{bc+1}{bc+1}.
\frac{10}{7}=\frac{a\left(bc+1\right)+c}{bc+1}
Since \frac{a\left(bc+1\right)}{bc+1} and \frac{c}{bc+1} have the same denominator, add them by adding their numerators.
\frac{10}{7}=\frac{abc+a+c}{bc+1}
Do the multiplications in a\left(bc+1\right)+c.
\frac{abc+a+c}{bc+1}=\frac{10}{7}
Swap sides so that all variable terms are on the left hand side.
7\left(abc+a+c\right)=10\left(bc+1\right)
Multiply both sides of the equation by 7\left(bc+1\right), the least common multiple of bc+1,7.
7abc+7a+7c=10\left(bc+1\right)
Use the distributive property to multiply 7 by abc+a+c.
7abc+7a+7c=10bc+10
Use the distributive property to multiply 10 by bc+1.
7abc+7a=10bc+10-7c
Subtract 7c from both sides.
\left(7bc+7\right)a=10bc+10-7c
Combine all terms containing a.
\left(7bc+7\right)a=10bc-7c+10
The equation is in standard form.
\frac{\left(7bc+7\right)a}{7bc+7}=\frac{10bc-7c+10}{7bc+7}
Divide both sides by 7bc+7.
a=\frac{10bc-7c+10}{7bc+7}
Dividing by 7bc+7 undoes the multiplication by 7bc+7.
a=\frac{10bc-7c+10}{7\left(bc+1\right)}
Divide 10bc-7c+10 by 7bc+7.
