(x+1)/5 =(3x-9)/3

\frac{x + 1}{5} = \frac{3 x - 9}{3}

x = 4

Solution steps

\frac{x + 1}{5} = \frac{3 x - 9}{3}

Apply fraction cross multiply: if

\frac{a}{b} = \frac{c}{d}

then

a \cdot d = b \cdot c

(x + 1) \cdot 3 = 5 (3 x - 9)

Expand

(x + 1) \cdot 3 : 3 x + 3

Expand

5 (3 x - 9) : 15 x - 45

3 x + 3 = 15 x - 45

Move

3

to the right side

3 x = 15 x - 48

Move

15 x

to the left side

- 12 x = - 48

Divide both sides by

- 12

x = 4

13 = 4 x - 11

y, x + y = 6

2 (\frac{1}{3} g - 8) = g

2 a = - 2 + 4 (a + 3)

lo g_{2} (3) = x
