8x - 4 = 7x - 1

First, add 4 to both sides. / Your problem should look like: 8x = 7x - 1 + 4
Second, simplify 7x - 1 + 4 to 7x + 3. / Your problem should look like: 8x = 7x + 3
Third, subtract 7x from both sides. / Your problem should look like: 8x - 7x = 3
Fourth, simplify 8x - 7x to x. / Your problem should look like: x = 3

Answer: x = 3
