(5x+4)/7 =(-3x+12)/3

\frac{5 x + 4}{7} = \frac{- 3 x + 12}{3}

x = 2

Solution steps

\frac{5 x + 4}{7} = \frac{- 3 x + 12}{3}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

(5 x + 4) \cdot 3 = 7 (- 3 x + 12)

Expand

(5 x + 4) \cdot 3 : 15 x + 12

Expand

7 (- 3 x + 12) : - 21 x + 84

15 x + 12 = - 21 x + 84

Move

12

to the right side

15 x = - 21 x + 72

Move

21 x

to the left side

36 x = 72

Divide both sides by

36

x = 2

- 2 (t + 8) = 12

2 x^{2} + 5 x - 18 = 0

\frac{3}{5} \geq \frac{2}{5}

\frac{1}{4} (16 x - 12 y + 4 z)

h^{3} - 1
