\frac{4}{7}x-4=x\times \frac{7}{15}+4\times \frac{7}{15}
Use the distributive property to multiply x+4 by \frac{7}{15}.
\frac{4}{7}x-4=x\times \frac{7}{15}+\frac{4\times 7}{15}
Express 4\times \frac{7}{15} as a single fraction.
\frac{4}{7}x-4=x\times \frac{7}{15}+\frac{28}{15}
Multiply 4 and 7 to get 28.
\frac{4}{7}x-4-x\times \frac{7}{15}=\frac{28}{15}
Subtract x\times \frac{7}{15} from both sides.
\frac{11}{105}x-4=\frac{28}{15}
Combine \frac{4}{7}x and -x\times \frac{7}{15} to get \frac{11}{105}x.
\frac{11}{105}x=\frac{28}{15}+4
Add 4 to both sides.
\frac{11}{105}x=\frac{28}{15}+\frac{60}{15}
Convert 4 to fraction \frac{60}{15}.
\frac{11}{105}x=\frac{28+60}{15}
Since \frac{28}{15} and \frac{60}{15} have the same denominator, add them by adding their numerators.
\frac{11}{105}x=\frac{88}{15}
Add 28 and 60 to get 88.
x=\frac{88}{15}\times \frac{105}{11}
Multiply both sides by \frac{105}{11}, the reciprocal of \frac{11}{105}.
x=\frac{88\times 105}{15\times 11}
Multiply \frac{88}{15} times \frac{105}{11} by multiplying numerator times numerator and denominator times denominator.
x=\frac{9240}{165}
Do the multiplications in the fraction \frac{88\times 105}{15\times 11}.
x=56
Divide 9240 by 165 to get 56.
