7+0.2x=5+0.3x

7 + 0.2 x = 5 + 0.3 x

x = 20

Solution steps

7 + 0.2 x = 5 + 0.3 x

Multiply both sides by

10

70 + 2 x = 50 + 3 x

Move

70

to the right side

2 x = 3 x - 20

Move

3 x

to the left side

- x = - 20

Divide both sides by

- 1

x = 20

x, 2 y^{2} x - y^{2} - (1 + 3 y) = x

g, m g = 7

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

lo g_{10} (2) (x + 1) + lo g_{10} (2) (x - 1) = 3

- 5 + x = 13
