(4x-3)/5 =(7x-9)/8

\frac{4 x - 3}{5} = \frac{7 x - 9}{8}

x = 7

Solution steps

\frac{4 x - 3}{5} = \frac{7 x - 9}{8}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

(4 x - 3) \cdot 8 = 5 (7 x - 9)

Expand

(4 x - 3) \cdot 8 : 32 x - 24

Expand

5 (7 x - 9) : 35 x - 45

32 x - 24 = 35 x - 45

Move

24

to the right side

32 x = 35 x - 21

Move

35 x

to the left side

- 3 x = - 21

Divide both sides by

- 3

x = 7
