expand (2x+5y=1,9)(3x-4y=-6)

expand

(2 x + 5 y = 1, 9) (3 x - 4 y = - 6)

2 \cdot 3 xx - 2 \cdot 4 x y = - 2 \cdot 6 x + 5 y = 1, 9 \cdot 3 x - 5 y = 1, 9 \cdot 4 y = - 5 y = 1, 9 \cdot 6

Solution steps

(2 x + 5 y = 1, 9) (3 x - 4 y = - 6)

= (2 x + 5 \cdot 1 \cdot 9 =, y) (3 x - 4 = y - 6)

Distribute parentheses

2 x \cdot 3 x + 2 x (- 4 y =) + 2 x (- 6) + 5 y = 1, 9 \cdot 3 x + 5 y = 1, 9 (- 4 y =) + 5 y = 1, 9 (- 6)

Apply minus-plus rules

+ (- a) = - a

2 \cdot 3 xx - 2 \cdot 4 x y = - 2 \cdot 6 x + 5 y = 1, 9 \cdot 3 x - 5 y = 1, 9 \cdot 4 y = - 5 y = 1, 9 \cdot 6

(1 - ln (x - 1))^{2}

(x + 5 y = 5,) - (- x + y = - 1)

3 (x + 3, 3 + y) + (2 y - 1, - 3 x + 11)

(2 x) (ln (x) - x = 0)

(x + y = 18, 6) (2 x + 4 y = 570)
