expand 4(0.4y=0.3x+1.2)

expand

4 (0.4 y = 0.3 x + 1.2)

1.6 y = 0.3 x + 4.8

Solution steps

4 (0.4 y = 0.3 x + 1.2)

= 4 (0.4 \cdot 0.3 = x y + 1.2)

Apply the distributive law:

a (b + c) = ab + a c

a = 4, b = 0.4 y = 0.3 x, c = 1.2

4 \cdot 0.4 y = 0.3 x + 4 \cdot 1.2

Simplify

4 \cdot 0.4 y = 0.3 x + 4 \cdot 1.2 : 1.6 y = 0.3 x + 4.8

1.6 y = 0.3 x + 4.8

\frac{2}{x} \frac{2}{x}

\frac{1}{( 2 y + 3 ) ^{2}}

\frac{( x + 6 ) ( x - 2 )}{( x + 3 ) ( x - 4 )}

(l, m, n) (1 - 4 - 2)

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