7x-2*(x+1)=0

7 x - 2 \cdot (x + 1) = 0

x = \frac{2}{5}

Solution steps

7 x - 2 (x + 1) = 0

Expand

- 2 (x + 1) : - 2 x - 2

7 x - 2 x - 2 = 0

Add similar elements:

7 x - 2 x = 5 x

5 x - 2 = 0

Move

2

to the right side

5 x = 2

Divide both sides by

5

x = \frac{2}{5}

∣ 2 x - 3 ∣ = 17

∣ 3 x - 4 ∣ = ∣ 2 x + 3 ∣

(2 - 3 i) (4 + 7 i)

\frac{4 i}{1 + i}
