0.4(3x-1)=0.5x+1

0.4 (3 x - 1) = 0.5 x + 1

x = 2

Solution steps

0.4 (3 x - 1) = 0.5 x + 1

Multiply both sides by

10

4 (3 x - 1) = 5 x + 10

Expand

4 (3 x - 1) : 12 x - 4

12 x - 4 = 5 x + 10

Move

4

to the right side

12 x = 5 x + 14

Move

5 x

to the left side

7 x = 14

Divide both sides by

7

x = 2

x, x + y = 380 x + 250 y

x - 3 x + 42 = 0

1 x = 2, \frac{h ( x , o )}{o _{3}}

f, g (- 2) = f + 2

f (2 + i) = (2 + i)^{2} + 3 (2 + i) - 7
