d(-15)[(-7)4]=[(-15)x]4

d \cdot (- 15) [(- 7) \cdot 4] = [(- 15) \cdot x] \cdot 4

x = - 7 d

Solution steps

d (- 15) [(- 7) \cdot 4] = [(- 15) x] \cdot 4

Switch sides

[(- 15) x] \cdot 4 = d (- 15) [(- 7) \cdot 4]

Remove parentheses:

(a) = a, - (- a) = a

[(- 15) x] \cdot 4 = d \cdot 15 \cdot 7 \cdot 4

Multiply the numbers:

15 \cdot 7 \cdot 4 = 420

[(- 15) x] \cdot 4 = 420 d

Divide both sides by

- 60

x = - 7 d

x, x - 3 y = 20

x, z = f^{1} (y + 2 x) + f^{2} (y - 3 x)

8 x = - 7

\frac{6 - x}{4} = \frac{x}{8}

x, m (5 - x) = 2 - y
