4(x-1)2-13(x-1)+9=0

4 (x - 1) 2 - 13 (x - 1) + 9 = 0

x = \frac{14}{5}

Decimal Notation

x = 2.8

Solution steps

4 (x - 1) \cdot 2 - 13 (x - 1) + 9 = 0

Multiply the numbers:

4 \cdot 2 = 8

8 (x - 1) - 13 (x - 1) + 9 = 0

Add similar elements:

8 (x - 1) - 13 (x - 1) = - 5 (x - 1)

- 5 (x - 1) + 9 = 0

Move

9

to the right side

- 5 (x - 1) = - 9

Divide both sides by

- 5

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

Move

1

to the right side

x = \frac{14}{5}

x, x - y = - 6

x, - 3 x + y = 2

x, x + y = \frac{3}{2}

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

13 = 11 - 4 x
