0.4y+0.8(4)=0.5(y+4)

0.4 y + 0.8 (4) = 0.5 (y + 4)

y = 12

Solution steps

0.4 y + 0.8 (4) = 0.5 (y + 4)

Remove parentheses:

(a) = a

0.4 y + 0.8 \cdot 4 = 0.5 (y + 4)

Multiply the numbers:

0.8 \cdot 4 = 3.2

0.4 y + 3.2 = 0.5 (y + 4)

Multiply both sides by

10

4 y + 32 = 5 (y + 4)

Expand

5 (y + 4) : 5 y + 20

4 y + 32 = 5 y + 20

Move

32

to the right side

4 y = 5 y - 12

Move

5 y

to the left side

- y = - 12

Divide both sides by

- 1

y = 12

x, 3 x + 4 y - 2 = 0

x, 3 x + 4 y - 5 = 0

x + \frac{1}{2} + \frac{3}{2} i = 0

c, y^{2} = - 6 x^{2} + c

2 x + 3 (x - 3) = 9 - x
