u-(4-2u)=7(u-1)

u - (4 - 2 u) = 7 (u - 1)

u = \frac{3}{4}

Decimal Notation

u = 0.75

Solution steps

u - (4 - 2 u) = 7 (u - 1)

Expand

u - (4 - 2 u) : 3 u - 4

Expand

7 (u - 1) : 7 u - 7

3 u - 4 = 7 u - 7

Move

4

to the right side

3 u = 7 u - 3

Move

7 u

to the left side

- 4 u = - 3

Divide both sides by

- 4

u = \frac{3}{4}

x, y - 1 = - 1 (x - 1)

\frac{1 - x}{15} = \frac{5 ^{- 1}}{2 ^{- 1}}

- 4 (x + 5) = \frac{5}{3} (3 x - 12)

2 x - 1 + i = 3 + i

\frac{1}{64} = (\frac{1}{4})^{3}
