a/4 =(a-3)/3

\frac{a}{4} = \frac{a - 3}{3}

a = 12

Solution steps

\frac{a}{4} = \frac{a - 3}{3}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

a \cdot 3 = 4 (a - 3)

Expand

4 (a - 3) : 4 a - 12

a \cdot 3 = 4 a - 12

Move

4 a

to the left side

- a = - 12

Divide both sides by

- 1

a = 12

[2 x - 6] = 16

(7 x + 5)^{2} = 14

(2 y + 5) (y - 4) = 0

x^{2} = 21 x
