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

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

x = - \frac{1}{40}

Decimal Notation

x = - 0.025

Solution steps

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

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

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

Expand

(3 + 5 x) \cdot 7 : 21 + 35 x

Expand

5 (4 - x) : 20 - 5 x

21 + 35 x = 20 - 5 x

Move

21

to the right side

35 x = - 5 x - 1

Move

5 x

to the left side

40 x = - 1

Divide both sides by

40

x = - \frac{1}{40}

(\frac{256}{81})^{\frac{1}{4}}

\frac{1}{2} + 2 \cdot \frac{2}{3}

\frac{x ^{5}}{x ^{6}}

3 w - 6 = 21

y^{2} - 12 y + 36 = 0
