0.3x+0.5x=24

0.3 x + 0.5 x = 24

x = 30

Solution steps

0.3 x + 0.5 x = 24

Add similar elements:

0.3 x + 0.5 x = 0.8 x

0.8 x = 24

Multiply both sides by

10

8 x = 240

Divide both sides by

8

x = 30

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

3.5 y + 2 = 19

x, (3 x + y - z) \cdot p + (x + y - z) \cdot q = 2 (x - y)

0.0025 = (\frac{2}{5})^{a} x 1 0^{b}

lo g_{10} (0.4) (8 + 2 x) = 1
