0.4x-0.2(40+x)=-0.05(40)

0.4 x - 0.2 (40 + x) = - 0.05 (40)

x = 30

Solution steps

0.4 x - 0.2 (40 + x) = - 0.05 (40)

Remove parentheses:

(a) = a

0.4 x - 0.2 (40 + x) = - 0.05 \cdot 40

Multiply the numbers:

0.05 \cdot 40 = 2

0.4 x - 0.2 (40 + x) = - 2

Multiply both sides by

10

4 x - 2 (40 + x) = - 20

Expand

4 x - 2 (40 + x) : 2 x - 80

2 x - 80 = - 20

Move

80

to the right side

2 x = 60

Divide both sides by

2

x = 30

8 x^{2} - 18 x + 9

20 m + m = 3

\frac{1}{9} \cdot \frac{1}{3}

x^{2} + 18 = 9 x

\frac{9}{10} = \frac{d}{6.4}
