3(4-r)=0.5(6+2r)

3 (4 - r) = 0.5 (6 + 2 r)

r = \frac{9}{4}

Decimal Notation

r = 2.25

Solution steps

3 (4 - r) = 0.5 (6 + 2 r)

Multiply both sides by

10

30 (4 - r) = 5 (6 + 2 r)

Expand

30 (4 - r) : 120 - 30 r

Expand

5 (6 + 2 r) : 30 + 10 r

120 - 30 r = 30 + 10 r

Move

120

to the right side

- 30 r = 10 r - 90

Move

10 r

to the left side

- 40 r = - 90

Divide both sides by

- 40

r = \frac{9}{4}

\frac{3.14 \cdot x}{4} = 27265.91

0.15 (5 x - 2) = 0.4 (x + 1)

r = (1 + i)^{16}

a = (4 x - 1) \cdot (x + 3) - 4 x \cdot (x - 1) + 7 x

x, x + 5 y = - 21
