((4+x))/7-((x+6))/3 =-1

\frac{( 4 + x )}{7} - \frac{( x + 6 )}{3} = - 1

x = - \frac{9}{4}

Decimal

x = - 2.25

Solution steps

\frac{( 4 + x )}{7} - \frac{( x + 6 )}{3} = - 1

\frac{4 + x}{7} - \frac{x + 6}{3} = - 1

Multiply by LCM

3 (x + 4) - 7 (x + 6) = - 21

Expand

3 (x + 4) - 7 (x + 6) : - 4 x - 30

- 4 x - 30 = - 21

Move

30

to the right side

- 4 x = 9

Divide both sides by

- 4

x = - \frac{9}{4}

3 x + 2 = 27

\frac{( 3 x - 1 )}{5} = 4

y, 8 y = 6 x^{2} - 10 x - 5 x^{- 2}

x, [f]^{2} - [f]^{2} = f

\frac{( \frac{( 2 x )}{5} - 1 )}{( - 5 )} = \frac{1}{7}
