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

x = 0

Solution steps

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

Group like terms

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

Add similar elements:

x + x = 2 x

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

Add the numbers:

3 + 1 = 4

2 x + 4 = 4 (x + 1)

Expand

4 (x + 1) : 4 x + 4

2 x + 4 = 4 x + 4

Move

4

to the right side

2 x = 4 x

Move

4 x

to the left side

- 2 x = 0

Divide both sides by

- 2

x = 0

7 j = 8 j - 3

4 - 7 (2 n + 1) = 2 (3 - 5 n)

\frac{3 x - 1}{7} + \frac{2 x - 1}{3} = x

(3 x - 7)^{2} - 5 (2 x + 1) (x - 2) = - x^{2} - [- (3 x + 1)]
