(4x-1)/3 =(12x-3)/7

\frac{4 x - 1}{3} = \frac{12 x - 3}{7}

x = \frac{1}{4}

Decimal Notation

x = 0.25

Solution steps

\frac{4 x - 1}{3} = \frac{12 x - 3}{7}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

(4 x - 1) \cdot 7 = 3 (12 x - 3)

Expand

(4 x - 1) \cdot 7 : 28 x - 7

Expand

3 (12 x - 3) : 36 x - 9

28 x - 7 = 36 x - 9

Move

7

to the right side

28 x = 36 x - 2

Move

36 x

to the left side

- 8 x = - 2

Divide both sides by

- 8

x = \frac{1}{4}

4 x - 6 = 16

x + \frac{4}{5} = 8 \frac{9}{10}

11 = \frac{4}{5} h - 1

\frac{1}{3} (9 x + 24) = 8 + 3 x

h, A = 4 h
