x/(3+4)=(x-3)/2

\frac{x}{3 + 4} = \frac{x - 3}{2}

x = \frac{21}{5}

Decimal Notation

x = 4.2

Solution steps

\frac{x}{3 + 4} = \frac{x - 3}{2}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

x \cdot 2 = (3 + 4) (x - 3)

Simplify

x \cdot 2 = 7 (x - 3)

Expand

7 (x - 3) : 7 x - 21

x \cdot 2 = 7 x - 21

Move

7 x

to the left side

- 5 x = - 21

Divide both sides by

- 5

x = \frac{21}{5}

- 7 + a = 13 - \frac{2}{3} a

- (x + 8) + 2 = 2.6 x - (x + 8.6)

- 4 (- 5 x + 6) = - 3 (- 4 x + 5)

4 (2 x + 1) = - 12 (x - 1) + 4 x

x, 9 y - 8 x = 25
