I. Elena began to solve this equation:
12x + 6(4x + 3)
= 2(6x +4-2)
3
12x + 6(4x + 3) = 3(2(6x + 4) - 2)
12x + 6(4x + 2) = 6(6x + 4) - 6
12x + 24x + 18 = 36x + 24 - 6
When she got to the last line, she stopped and said the equation is true for all values of x (infinite solutions).
low could Elena tell?
