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

\frac{x}{4} = \frac{( 3 - x )}{5}

x = \frac{4}{3}

Decimal Notation

x = 1.33333 \dots

Solution steps

\frac{x}{4} = \frac{( 3 - x )}{5}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

x \cdot 5 = 4 (3 - x)

Expand

4 (3 - x) : 12 - 4 x

x \cdot 5 = 12 - 4 x

Move

4 x

to the left side

9 x = 12

Divide both sides by

9

x = \frac{4}{3}

y = - 3^{3}

6 (2 m - 5) = 8 (3 m + 6)

- 6 k + 3 = - 3 (- 3 - 6 k)

ln (\frac{1}{e ^{3}}) = - 3

x, 0 = x + y
