2x+1=x-4(x+3)

2 x + 1 = x - 4 (x + 3)

x = - \frac{13}{5}

Decimal Notation

x = - 2.6

Solution steps

2 x + 1 = x - 4 (x + 3)

Expand

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

2 x + 1 = x - 4 x - 12

Add similar elements:

x - 4 x = - 3 x

2 x + 1 = - 3 x - 12

Move

1

to the right side

2 x = - 3 x - 13

Move

3 x

to the left side

5 x = - 13

Divide both sides by

5

x = - \frac{13}{5}

- 3 (2 r + 7) = 3

- 5 = n - 3

\frac{1}{2} (x + 3) = 2 (x - 3)

4 x + 27 = 10 x - 33

(x + 7) (x - 2) = (x + 1)^{2}
