3x+4x+5x=4(x+2)

3 x + 4 x + 5 x = 4 (x + 2)

x = 1

Solution steps

3 x + 4 x + 5 x = 4 (x + 2)

Add similar elements:

3 x + 4 x + 5 x = 12 x

12 x = 4 (x + 2)

Expand

4 (x + 2) : 4 x + 8

12 x = 4 x + 8

Move

4 x

to the left side

8 x = 8

Divide both sides by

8

x = 1

f = (\frac{1}{3})^{1}

- 2 y + 6 = - 12

x, - 4 x + y = 6

r, I = p r t

\frac{8}{11} = \frac{X + 1}{33}
