3(1-5/2 x)+4x=5

3 (1 - \frac{5}{2} x) + 4 x = 5

x = - \frac{4}{7}

Decimal Notation

x = - 0.57142 \dots

Solution steps

3 (1 - \frac{5}{2} x) + 4 x = 5

Expand

3 (1 - \frac{5}{2} x) + 4 x : 3 - \frac{7}{2} x

3 - \frac{7}{2} x = 5

Multiply both sides by

2

6 - 7 x = 10

Move

6

to the right side

- 7 x = 4

Divide both sides by

- 7

x = - \frac{4}{7}

2 (2)^{3}

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

11 - \frac{x}{6} = - 11

(- \frac{4}{3}) \cdot (- \frac{3}{7})

\frac{8 - 2 i}{- 9 - 12 i}
