(3a-11)/8 =(a+9)/4

\frac{3 a - 11}{8} = \frac{a + 9}{4}

a = 29

Solution steps

\frac{3 a - 11}{8} = \frac{a + 9}{4}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

(3 a - 11) \cdot 4 = 8 (a + 9)

Expand

(3 a - 11) \cdot 4 : 12 a - 44

Expand

8 (a + 9) : 8 a + 72

12 a - 44 = 8 a + 72

Move

44

to the right side

12 a = 8 a + 116

Move

8 a

to the left side

4 a = 116

Divide both sides by

4

a = 29

f, N^{2} = 6 f + H

2 (u - 9) = 4

2 x = 15 + x

\frac{7 x - 1}{2} = 13 - x

a, \frac{a}{b} = 0
