Pablo solved the equation ax + b = c(x + d) + e for x using the steps shown below.

ax + b = c(x + d) + e

b = c(x + d) + e – ax

b = cx + cd + e – ax

b = x(c – a) + cd + e

b – cd + e = x(c – a)

Whats Pablo's error?

Pablo solved the equation ax + b = c(x + d) + e for x using the steps shown below.

ax + b = c(x + d) + e

        b = c(x + d) + e – ax

        b = cx + cd + e – ax

        b = x(c – a) + cd + e

b – cd + e = x(c – a)
