0.18a+0.4(10-a)=0.2(10)

Solution

0.18 a + 0.4 (10 - a) = 0.2 (10)

Solution

a = \frac{100}{11}

+1

Solution steps

0.18 a + 0.4 (10 - a) = 0.2 (10)

Remove parentheses:

(a) = a

0.18 a + 0.4 (10 - a) = 0.2 \cdot 10

Multiply the numbers:

0.2 \cdot 10 = 2

0.18 a + 0.4 (10 - a) = 2

Multiply both sides by

100

18 a + 40 (10 - a) = 200

Expand

18 a + 40 (10 - a) : - 22 a + 400

- 22 a + 400 = 200

Move

400

to the right side

- 22 a = - 200

Divide both sides by

- 22

a = \frac{100}{11}
