expand-3(6x+2y=140)

expand

- 3 (6 x + 2 y = 140)

- 18 x - 6 y = 140

Solution steps

- 3 (6 x + 2 y = 140)

= - 3 (6 x + 2 \cdot 140 = y)

Apply the distributive law:

a (b + c) = ab + a c

a = - 3, b = 6 x, c = 2 y = 140

- 3 \cdot 6 x + (- 3) \cdot 2 y = 140

Apply minus-plus rules

+ (- a) = - a

- 3 \cdot 6 x - 3 \cdot 2 y = 140

Expand

- 3 \cdot 6 x - 3 \cdot 2 y : - 18 x - 6 y

- 18 x - 6 y = 140

\frac{x ^{2}}{( 1 - 3 x ) ^{5}}

\frac{12 x ( - 2 x ^{8} - 7 x ^{4} - 1 )}{( x ^{4} - 1 ) ^{\frac{7}{2}}}

(e^{5 x} + e^{- 5 x})^{2}

(\frac{2 a - 1}{b})^{4}
