(a+7)/3 =(a-3)/5

\frac{a + 7}{3} = \frac{a - 3}{5}

a = - 22

Solution steps

\frac{a + 7}{3} = \frac{a - 3}{5}

Apply fraction cross multiply: if

\frac{a}{b} = \frac{c}{d}

then

a \cdot d = b \cdot c

(a + 7) \cdot 5 = 3 (a - 3)

Expand

(a + 7) \cdot 5 : 5 a + 35

Expand

3 (a - 3) : 3 a - 9

5 a + 35 = 3 a - 9

Move

35

to the right side

5 a = 3 a - 44

Move

3 a

to the left side

2 a = - 44

Divide both sides by

2

a = - 22

\frac{2 + 3 i}{2 + i}

5 x^{2} + x + 3 = 0

x^{2} + (2 x)^{2} = 1 5^{2}

\frac{x ^{a}}{x ^{b}}

- 2 x + 5 > 9
