(x+4)/3-x/7 =(x+7)/5

\frac{x + 4}{3} - \frac{x}{7} = \frac{x + 7}{5}

x = - 7

Solution steps

\frac{x + 4}{3} - \frac{x}{7} = \frac{x + 7}{5}

Multiply by LCM

35 (x + 4) - 15 x = 21 (x + 7)

Expand

35 (x + 4) - 15 x : 20 x + 140

Expand

21 (x + 7) : 21 x + 147

20 x + 140 = 21 x + 147

Move

140

to the right side

20 x = 21 x + 7

Move

21 x

to the left side

- x = 7

Divide both sides by

- 1

x = - 7

x (1 - b) - y (1 - b)

x^{2} - 15 x + 36

- 1.5 (t - 2) = - 10.5

(\frac{81}{169})^{\frac{1}{2}}

x^{2} + 16 x + 62 = 0
