expand 2(3x+4y=-12)

expand

2 (3 x + 4 y = - 12)

6 x + 8 y = - 24

Solution steps

2 (3 x + 4 y = - 12)

= 2 (3 x + 4 = y - 12)

Distribute parentheses

2 \cdot 3 x + 2 \cdot 4 y = 2 (- 12)

Apply minus-plus rules

+ (- a) = - a

2 \cdot 3 x + 2 \cdot 4 y = - 2 \cdot 12

Simplify

2 \cdot 3 x + 2 \cdot 4 y = - 2 \cdot 12 : 6 x + 8 y = - 24

6 x + 8 y = - 24

R e (x + \frac{1}{x})^{4}

\frac{y ^{2} - 1}{y ( x + 2 )}

\frac{20}{( x - 4 ) ( x + 1 )}

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

(e - 5) (f - 2 g)
