x-x*0.1=100

x - x \cdot 0.1 = 100

x = \frac{1000}{9}

Decimal Notation

x = 111.11111 \dots

Solution steps

x - x \cdot 0.1 = 100

Add similar elements:

x - 0.1 x = 0.9 x

0.9 x = 100

Multiply both sides by

10

9 x = 1000

Divide both sides by

9

x = \frac{1000}{9}

2 a + x = 4

1 1^{10} \cdot 15 - 1 1^{11} (x - 5) = 11 4^{10}

12 - 3 x = - 25

3 \cdot (x - 2)^{2} \cdot (x + 5) = 3 \cdot (x + 1)^{2} \cdot (x - 1) + 3

m = 12 j - r
