expand (3x+5y=3,3)(12x-7y=51)

expand

(3 x + 5 y = 3, 3) (12 x - 7 y = 51)

36 x^{2} - 21 x y = 51

Solution steps

(3 x + 5 y = 3, 3) (12 x - 7 y = 51)

= (3 x + 5 \cdot 3 \cdot 3 =, y) (12 x - 7 \cdot 51 = y)

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = 3 x, b = 5 y = 3, 3, c = 12 x, d = - 7 y = 51

3 x \cdot 12 x + 3 x (- 7 y = 51) + 5 y = 3, 3 \cdot 12 x + 5 y = 3, 3 (- 7 y = 51)

Apply minus-plus rules

+ (- a) = - a

3 \cdot 12 xx - 3 \cdot 7 x y = 51 + 5 y = 3, 3 \cdot 12 x - 5 y = 3, 3 \cdot 7 y = 51

Expand

3 \cdot 12 xx - 3 \cdot 7 x y : 36 x^{2} - 21 x y

36 x^{2} - 21 x y = 51

ln (q) (- \frac{1}{a} - 1)

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

- \frac{5}{81} (9 e^{9 x} x - e^{9 x})

A^{'} (t) (π (2 - t)^{2})
