(4-x)/2 =(7+x)/4

\frac{4 - x}{2} = \frac{7 + x}{4}

x = \frac{1}{3}

Decimal Notation

x = 0.33333 \dots

Solution steps

\frac{4 - x}{2} = \frac{7 + x}{4}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

(4 - x) \cdot 4 = 2 (7 + x)

Expand

(4 - x) \cdot 4 : 16 - 4 x

Expand

2 (7 + x) : 14 + 2 x

16 - 4 x = 14 + 2 x

Move

16

to the right side

- 4 x = 2 x - 2

Move

2 x

to the left side

- 6 x = - 2

Divide both sides by

- 6

x = \frac{1}{3}

5 x + 3 = - 12

3 x - 7 = 1 + x

\frac{2 x + a}{b} - \frac{b - x}{a} = \frac{3 a x + ( a - b ) ^{2}}{ab}

x, 200 x - 10 y + 1000 = 0

x, - 2 x + 5 y = - 28
