expand (7x+3y=-2,6)(4x+y=-4)

expand

(7 x + 3 y = - 2, 6) (4 x + y = - 4)

7 \cdot 4 xx + 7 x y = - 7 \cdot 4 x + 3 y = 4 x + 3 y = y = - 3 y = 4 - 2, 6 \cdot 4 x - 2, 6 y = 2, 6 \cdot 4

Solution steps

(7 x + 3 y = - 2, 6) (4 x + y = - 4)

= (7 x + 3 = y - 2 \cdot 6,) (4 x + = y - 4)

Distribute parentheses

7 x \cdot 4 x + 7 x y = 7 x (- 4) + 3 y = 4 x + 3 y = y = 3 y = (- 4) + (- 2, 6) \cdot 4 x + (- 2, 6) y = (- 2, 6) (- 4)

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

7 \cdot 4 xx + 7 x y = - 7 \cdot 4 x + 3 y = 4 x + 3 y = y = - 3 y = 4 - 2, 6 \cdot 4 x - 2, 6 y = 2, 6 \cdot 4

\frac{\partial}{\partial u} ((f (u)) (1, - 1))

\frac{( 120 - x ) ^{2}}{4}

(\frac{3 x - y}{3})^{14}

\frac{( 16 + x - 4 ) ( x + 2 ) ( 9 + x + 3 )}{x}

\frac{1}{( x ^{2} + 1 ) ^{4}}
