x/5-(2-x)/4 =3

\frac{x}{5} - \frac{2 - x}{4} = 3

x = \frac{70}{9}

Decimal Notation

x = 7.77777 \dots

Solution steps

\frac{x}{5} - \frac{2 - x}{4} = 3

Multiply by LCM

4 x - 5 (- x + 2) = 60

Expand

- 5 (- x + 2) : 5 x - 10

4 x + 5 x - 10 = 60

Add similar elements:

4 x + 5 x = 9 x

9 x - 10 = 60

Move

10

to the right side

9 x = 70

Divide both sides by

9

x = \frac{70}{9}

∣ 1 - 3 a ∣ = 29

x^{4} - 7 x^{3}

\frac{3 x}{2} \geq 30

8 + 8

2 ∣ 2 x - 3 ∣ + 12 > 14
