1x+3(x+1)-1=5

1 x + 3 (x + 1) - 1 = 5

x = \frac{3}{4}

Decimal Notation

x = 0.75

Solution steps

1 \cdot x + 3 (x + 1) - 1 = 5

Multiply:

1 \cdot x = x

x + 3 (x + 1) - 1 = 5

Move

1

to the right side

x + 3 (x + 1) = 6

Expand

3 (x + 1) : 3 x + 3

x + 3 x + 3 = 6

Add similar elements:

x + 3 x = 4 x

4 x + 3 = 6

Move

3

to the right side

4 x = 3

Divide both sides by

4

x = \frac{3}{4}

f, f (f (n)) = n^{2}

x, 4 x + 3 = 10 y + 1

x, 3 y - 5 x = 9

4 x = (1 mod 7)

a, 58 a + 58 b = 116
